Abstract
Previous articles discussed striking analogies between the 7
different notes of the seven musical scales and their complements, the 7 unit
imaginary octonions and their 7 conjugates, the 7 Yang and 7 Yin meridians known
to acupuncture, the outermost (7+7) points of the Sri Yantra and the (7+7)
regular polygons of the inner Tree of Life. These similarities exist because
they are different manifestations of a universal, 14fold paradigm embodied in
the symmetry group PSL(2,7), which is isomorphic to the symmetry group SL(3,2)
of the Fano plane representation of the octonions, whose group of isomorphisms
is G_{2}, the rank2 exceptional group of dimension 14. Seven octaves of
the notes of the 7 scales are shown to constitute a holistic pattern. For
example, the composition of their notes conforms to the tetractys extrapolation
of Plato’s Lambda, the universal archetype governing holistic systems. Their
pattern of 91 intervals is identical to the tetractys representation of the 91
subplanes of the seven planes of consciousness, as is the pattern of
permutations of the unit imaginary octonions. As the perfect fifth of the fifth
octave and the 33rd Pythagorean note in the seven octaves of notes making up the
seven scales, the note with tone ratio 24 completes a sequence of ten overtones
and 22 fractional, Pythagorean tone ratios that matches the pattern of ten
Sephiroth and 22 Paths of the Tree of Life. The 92 notes in the seven octaves
are symbolized by the 92 yods lying on the boundaries of the last four enfolded,
regular polygons of the inner Tree of Life. Their counterparts in the disdyakis
triacontahedron are the four types of polygons formed by its vertices orthogonal
to the axis joining two diametrically opposite A vertices. The musical
counterpart of the 168 permutations of the seven unit imaginary octonions and
their conjugates are the 168 repetitions of all rising and falling intervals
between the notes in the seven scales. Divided into tetractyses, a heptagon has
91 yods symbolizing the 91 tone intervals in the seven octaves of the scales.
The 60 vertices of the disdyakis triacontahedron surrounding its axis denote the
60 intervals up to the tenth overtone. Its 180 edges denote the 180 notes and
tone intervals between successive notes in the seven octaves. The 168 edges
above or below the equator of the disdyakis triacontahedron signify the 168
repetitions of the rising and falling intervals between the notes in the seven
scales. The 12 edges marking its equator signify the 12 tone intervals below the
first octave. The pair of dodecagons with 1680 yods surrounding the centres of
their 24 sectors has its counterpart in the disdyakis triacontahedron with 24
vertices and edges in its equator as the 1680 geometrical elements that surround
its axis. In the polygonal Tree of Life, there are 168 yods associated with
either set of the first six enfolded polygons with 24 external corners. The
association of the number 24 with 168 also appears in the 24 heptagons of the
Klein Configuration, which denotes the 168 automorphisms of the Klein quartic
and whose tiling on a 3torus requires 168 triangles. It is found in the I Ching
table as the 168 lines and broken lines in the 56 trigrams above or below the
diagonal, which are seven copies of the eight trigrams with 24 lines and broken
lines.

The Sephiroth exist in the four Worlds of Atziluth, Beriah, Yetzirah
and Assiyah. Corresponding to them are the Godnames, Archangels, Order of
Angels and Mundane Chakras (their physical manifestation). This table gives
their number values obtained by the ancient practice of gematria, wherein a
number is assigned to each letter of the alphabet, thereby giving a number
value to a word that is the sum of the numbers of its letters.

1. The seven octaves of the seven musical
scales The Pythagorean musical scale consists of five tone intervals
of 9/8 (T) and two leimmas of 256/243 (L):
By starting with successive notes to generate scales of eight notes and then
normalising the tone ratios so that the tonic in each scale has a tone ratio of 1, the pattern
of intervals is repeated at the eighth sequence, thus generating seven distinct octave
species:
These are the musical modes^{1} used for hundreds of years in the plainsong of the Roman Catholic
Church. Mode 8 (Hypomixolydian) is the D scale with different ‘dominant’ and ‘finalis’
notes. Table 2 displays the values of their tone ratios.

Tone ratios belonging to the Pythagorean scale are written in black and
nonPythagorean tone ratios are written in red. The 42 notes between the tonic and the octave
comprise 26 notes with Pythagorean tone ratios and 16 with nonPythagorean
values. Table 1 indicates that 26 is the gematria number value of
YAHWEH, the Godname of Chokmah. As 42 is the 21st even integer, EHYEH, the
Godname of Kether with number value 21, prescribes the notes of the seven
musical scales between the tonic and the octave.
The seven species of octaves comprise 14 different notes. In order of
increasing tone ratios, they are:
1 256/243
9/8 32/27 81/64
4/3 1024/729
729/512 3/2 128/81 27/16 16/9 243/128 2
There are six Pythagorean intervals and six nonPythagorean intervals
between the tonic and octave. Defining the inversion of a note with tone ratio n as a note
with tone ratio m, where nm = 2, the 14 notes form seven pairs of notes and their
inversions:

1024/729×729/512 = 2

The inversion of a note is equal to the interval between it and the
octave.
Now imagine the 14 notes as composing a new musical scale. It is,
of course, not similar to the modern equaltempered scale because this has 13 notes with 12
equal halftone intervals. Table 3 shows the tones ratios of eight successive octaves of these notes.
For future discussion, it is unnecessary to regard these 14 notes as an actual musical scale
because we will be analysing seven octaves of the seven scales and it is more convenient to
group their notes and their higher octaves in order of increasing tone ratios in a
scalelike sequence than to consider them in their separate scales. 2^{7} = 128 is
the seventh octave. Table 3 indicates that it is the 92nd note, the 91st interval, the
49th Pythagorean interval, the
(Purple cells indicate overtones, black tone ratios are Pythagorean and
red tone ratios are nonPythagorean. The turquoise cell is 24, the perfect fifth of the fifth
octave).
50th Pythagorean note and the 21st
overtone. The appearance of the number values of the Godnames ELOHIM (50), EL
CHAI (49) and EHYEH (21) is the first sign that these seven
octaves constitute a Tree of Life pattern defines by the Godnames of the Sephiroth. Each
‘octave’ group of 13 notes has six Pythagorean notes other than octaves and nonPythagorean
notes, so that below the seventh octave there are 90 intervals made up of six octaves, (7×6=42)
Pythagorean notes and 42 nonPythagorean notes, that is, (42+42=84) intervals other than
octaves. As discusses later, the fact that there are 90 intervals is a sign that the seven
octaves of the notes in the seven musical scales constitutes a holistic pattern.
Now let us consider the tone ratio 24 in the turquoise cell of Table 3. It is the 33rd Pythagorean note, the 32nd Pythagorean interval, the
10th overtone, the 61st note and the 60th interval. As 32 is the 31st
integer after 1 and 61 is the 31st odd integer, the Godname EL with number
value 31 picks out the tone ratio 24 in the sequence of monotonically
increasing tone ratios of the notes of the seven scales and their higher octaves. There are
22 Pythagorean notes with fractional tone ratios and 28 fractional, nonPythagorean notes up
to 24, that is, 50 notes with fractional tone ratios. Hence, the
4
Godname ELOHIM with number value 50 also picks out this
note. There are 14 fractional, nonPythagorean notes, 6 fractional, Pythagorean notes (that is,
20 fractional notes) and 11 overtones above the tone ratio 24 to 128, that is,
(20+11=31) notes. EL therefore also defines the number of notes above it to
128. The fact that EL picks out 24 in not just one but three ways makes coincidence
implausible as the reason why two Godname numbers describe its position in the sequence of
notes.
The reason why such Godnames appear is that the 32 intervals and the ten
overtones up to the tone ratio 24 form a Tree of Life pattern, which is always prescribed by
all the Godnames. The 10 overtones correspond to the ten Sephiroth and the 22 notes with
fractional, Pythagorean tone ratios correspond to the 22 Paths of the Tree of Life
(Fig. 1).
The implication of this correspondence is that, in corresponding to Malkuth,
the last Sephirah, the tenth overtone 24 plays some role in the physics of matter. This will be
explored later.
24 is the tone ratio of the 61st note as well as the tenth overtone. A
decagon whose
5
sectors are tetractyses has 61 yods (Fig. 2). Called “All perfect” by the ancient Pythagoreans, the number 10
completes the sequence of natural integers because all integers above it are simply the sum
of integers smaller than it and integer multiples of 10 that are similarly reducible.
Assigning to its central yod the tone ratio 1 as the first note, the ten overtones up to 24
can be assigned to the corners of the decagon and the 50 notes below it
with fractional tone ratios can be assigned to the 50 hexagonal yods.
This is another reason for regarding the tone ratio 24 as special — it is defined
by the tetractysdivided decagon symbolizing the perfect number 10.
The Godname ADONAI with number value 65 prescribes the ten
lowest Trees of Life because they have 65 Sephiroth (Fig. 3). The values of its letters denote various groups of Sephiroth.
Assigning the musical notes of the seven scales to the Sephiroth, starting with Chesed of
the tenth tree — the first Sephirah of Construction — the note assigned to
6
the lowest Sephirah is 24 because it is the 61st. Here is further evidence
that this tone ratio has physical significance, for ADONAI is the Godname of Malkuth,
the physical universe. The 10tree is the representation of the Tree of Life with each Sephirah
represented by a tree. Remarkably, they both define the tone ratio 24 — in the former case as
the 32nd interval and in the latter case as the 61st note.
The note 24 divides the 70 fractional notes up to 128 into
50 below it and 20 above it, the 22 integer notes into 11 up to it and 11
above it and the 92 notes up to 128 into 60 below and 31 above it:
The 50:20 division of fractional notes up to the seventh
octave demonstrates that this sequence of 70 notes constitutes a Tree of Life pattern. This is
because, when the 16 triangles of the Tree of Life are tetractyses, it has 70 yods made up of
20 yods in the tetrahedron whose vertices coincide with the four lowest Sephiroth of
Construction and 50 yods in the rest of the tree (Fig. 4). The division 50:20 of its yods has its counterpart
in the inner Tree of Life as the 20 corners of the two dodecagons and the
50 corners of the two sets of six polygons. As we shall show later, the
dodecagon marks the tone ratio 24 in another way.
The 91 intervals up to 128 consist of 21 overtones and 70
fractional notes comprising 28 Pythagorean notes and 42 nonPythagorean notes. The 91 intervals
therefore comprise (21+28=49) Pythagorean notes and 42
nonPythagorean notes. Seven of the former are the notes of the Pythagorean scale above the
tone. Hence, 91 = 7 + 84, where 84 is the number of other notes in the seven octaves. 84 = 6 +
78, where 6 = the number of nonPythagorean notes in the first octave and 78 = 42 +
36, where 42 is the number of Pythagorean notes above the first octave and
36 is the number of non Pythagorean notes above the first octave. Therefore,
the 84 notes are divided into 42 Pythagorean notes above the first octave and 42
nonPythagorean notes (six in the first octave and 36 above it).
Alternatively, 84 intervals are not octaves.
Below is summarised how some Godnames prescribe either the seven octaves of
the seven musical scales as a Tree of Life pattern or the tone ratio 24 (the brackets enclose
their number values):
EHYEH (21):

21 overtones up to 128.
42 Pythagorean notes above the 1st octave (42 = 21st even
integer).
42 nonPythagorean notes in the seven octaves. 
YAH (15):

A 15sided polygon with tetractys sectors has 91
yods. 128 is the 91st
interval. 
YAHWEH (26):

24 is the 26th note, counting from the 2nd
octave. 
ELOHIM (50):

128 = 50th Pythagorean note.
50 notes below 24 with fractional tone ratios. 
EL (31):

24 = 32nd Pythagorean interval (32 = 31st integer
after 1).
31 notes above 24 to 128. 
ELOHA (36):

36 nonPythagorean notes and 36
Pythagorean notes other than
octaves above the 1st octave. 
7
YAHWEH ELOHIM (76): 
76 notes above 1st nonPythagorean note of 2nd
octave. 
EL CHAI (49): 
128 = 49th Pythagorean interval. 
2. Comparison
with the last four enfolded polygons
The inner form of the Tree of Life (Fig. 5) consists of two similar sets of seven regular polygons that are
enfolded in one another, all 14 polygons sharing the same ‘root edge.’ The last four
polygons are the hexagon, octagon, decagon and dodecagon. 92 yods lie on their 32 sides
outside their root edge (Fig. 6). Of these, 32 red yods lie on the 11 sides of the
dodecagon outside the root edge and 60 yods lie on the 21
edges of the hexagon, octagon and decagon. The Godname EHYEH with number value
21 prescribes the first three polygons with 60 yods on their edges, whilst the
Godname EL with number value 31 prescribes all seven polygons with 32 sides
because 32 is the 31st integer after 1. As the 32nd Pythagorean interval is 24
and the 92nd note is 128, the 92 yods in the last four polygons symbolize the 92 notes in the
seven octaves. The ten vertices of the dodecagon symbolize the ten overtones up to 24, the 22
yods on its edges
between vertices denote the 22 Pythagorean intervals up to 24 and the 60
yods of the hexagon, octagon & decagon denote the 60 remaining intervals. The dodecagon
defines the tone ratio 24 in terms of the correspondence between its boundary yods and the
notes in the Pythagorean scale up to 24. Alternatively, as 24 is the 61st note in the sequence
of notes and as there are 31 notes above it to the seventh octave, the 60 yods
in the first three polygons may be thought to symbolize the 60 notes below 24, whilst the 32
yods in the dodecagon denote 24 and the remaining 31 notes above 24. Whichever
correspondence one chooses (as it reproduces the order of sequence of notes, the latter is more
natural), it is clear that the tone ratio 24 is marked out either by the first three polygons
as the transition point to the last polygon or by the last one itself as having special
significance. The increase of pitch from note to note over seven octaves has its exact
counterpart in the sacred geometry of the last four polygons. Why? Because both conform to a
Tree of Life pattern.
This conclusion is given support by the fact that the first three polygons
of the inner Tree of Life — the triangle, square and pentagon — have 24 yods on their edges
8
outside the root edge (see Fig. 6). Once again, the part of the inner Tree of Life supplementing a part
that is itself a Tree of Life pattern defines the very same number 24! It is highly
implausible that this is merely coincidental. It speaks powerfully of design — of a
universal blueprint of which the seven musical scales and their seven octaves are a
manifestation and in which the tenth overtone plays a fundamental role, as indicated
previously by the fact that the Godname ELOHIM assigned to Binah in the Tree of Life
prescribes the number of fractional notes below 24 and the Godname EL of Chesed, the
next Sephirah, prescribes the 31 notes above it to 128.
As the first of the last four polygons with 92 yods on their edges, the
hexagon embodies the 91 intervals. This is because, when its six sectors are each divided into
three tetractyses, it has 91 yods (Fig 7). This is true also for the alternative construction out of a Star of
David. The 49 yods either delineating the edges of the tetractyses or
at their centres symbolize the 49 Pythagorean notes. The
42 yods inside each sector symbolize the 42 nonPythagorean intervals. This
is a remarkable example of how the tetractys generates Tree of Life parameters like the number
91.
3. The Cosmic Tetractys pattern of the seven
octaves As many previous articles have demonstrated, Pythagoras’
tetractys reveals numbers of cosmic significance embodied in objects possessing sacred
geometry when they are constructed from this building block. This remains true for its
next higherorder differentiation — the 2ndorder tetractys (Fig. 8), formed by replacing each yod in the
(1storder)
tetractys by a tetractys of the same order. It has 85 yods, where
85 = 4^{0} + 4^{1} + 4^{2} + 4^{3}.
9
10
84 yods surround its centre, where
84 = 1^{2} + 3^{2} + 5^{2} + 7^{2}.
They symbolize the 84 collective degrees of freedom or variables
characterising a holistic system’s physical manifestation, which is symbolized by the yod at
the centre of the central 1storder tetractys. It represents the Malkuth aspect of the Tree of
Life, whilst the six coloured yods at the corners of a hexagon symbolize the six Sephiroth of
Construction above Malkuth.
In the context of the seven musical scales, the central yod denotes the
seven Pythagorean intervals of the first octave and the 84 yods surrounding it denote the 42
Pythagorean notes above the first octave, the six nonPythagorean notes in the first octave and
the 36 nonPythagorean notes above the first octave. The lattermost are
symbolized by the 36 yods on the boundary of the 2ndorder tetractys.
Suppose that the central tetractys in the 2ndorder tetractys is replaced by
another 2ndorder tetractys. Its seven coloured tetractyses have (7×7=49)
hexagonal yods, whilst the six coloured tetractyses surrounding it that belong to the original
2ndorder tetractys have (6×7=42) hexagonal yods. The new kind of tetractys has
(49+42=91) hexagonal yods. This is the Cosmic Tetractys (Fig. 9). It maps all the levels of consciousness of the physical and
spiritual cosmos, as now explained. The seven Sephiroth of Construction are the objective
‘qualities’ of God that have been anthropomorphized into the gods and goddesses of ancient
religions. They define seven modalities of being. The great Swiss psychologist Carl G. Jung
explored the lowest four of these when he identified the four ‘psychic functions’ of
sensing, feeling, thinking and intuiting as ways of apprehending the world. In Theosophical
terms, the seven Sephiroth of Construction appear as the seven ‘principles’:
They also define as modalities of being the seven cosmic planes of
consciousness:
The six cosmic superphysical planes are each divided into seven subplanes,
totalling 42 subplanes. The cosmic physical plane is divided into seven planes (they have the
same names as above), each of which is further divided into seven subplanes, so that it
consists of 49 subplanes. There are therefore (42+49=91)
subplanes in the seven cosmic planes. This is the number of hexagonal yods in the Cosmic
Tetractys. Each yod symbolizes a subplane, the 49 hexagonal yods in the
central 2ndorder tetractys denoting the 49 subplanes of the cosmic physical
plane and the 42 hexagonal yods surrounding it denoting the 42 subplanes of the six cosmic
superphysical planes. Each hexagon containing seven yods denotes a plane of consciousness that
is divided into seven subplanes.
11
For future discussion, it will be useful to factorise 91 as 7×13, where 13 =
7 + 6 (the reason for the red colour will be apparent shortly).
Then 91 = 7(7+6) = 7×7 + 7×6 =
49 + 42. This factorisation reveals the fact
that 91 is the sum of the first 13 integers:
91 = 1 + 2 + 3 + … + 13,
i.e., it is the thirteenth triangular number. As 28 is the seventh
triangular number:
28 = 1 + 2 + 3 +… + 7,
the number 91 is the sum of 28 and 63. We found earlier that the 91 tone
intervals up to the seventh octave comprise 28 notes with fractional, Pythagorean tone ratios
and 63 others (21 overtones & (7×6=42) nonPythagorean notes — the
reason for writing in red). The number 7 defines through its triangular number the division of
the 91 intervals into 28 intervals with fractional Pythagorean tone ratios and 63 intervals
that are either nonPythagorean or overtones. Notice that the tone ratio 24 also defines this
28:63 division, for we found earlier that 28 fractional, nonPythagorean notes are below
it.
Comparing the seven planes of consciousness with the seven octaves, the
following correspondences appear:

7 planes

7 octaves

1. 
91 subplanes 
91 intervals 
2. 
49 subplanes of the cosmic physical plane 
49 Pythagorean intervals 
3. 
42 subplanes of the cosmic
superphysical plane 
42 nonPythagorean intervals 
4. 
28 subplanes of the 4 lowest planes
in the cosmic physical plane 
28 Pythagorean intervals with fractional tone ratios 
5. 
21 subplanes of the 3 highest planes
in the cosmic physical plane 
21 overtones 
Each subplane has a corresponding interval as its musical counterpart. The
counterpart of the cosmic physical plane with 49 subplanes is the set of
49 Pythagorean intervals. 28 of them have fractional tone ratios. Their
counterpart is the set of 28 subplanes comprising the four lowest planes of consciousness —
physical, astral, mental and buddhic — that correspond in Kabbalah to the four lowest Sephirah
of Construction — Malkuth, Yesod, Hod & Netzach. 21 of the
49 Pythagorean intervals are overtones. Their counterpart is the set of
21 subplanes of the three highest planes of
the cosmic physical plane — the Atmic, Anupadaka and Adi planes.
4. The Lambda Tetractys pattern of the seven
octaves In his Timaeus, his treatise on Pythagorean
cosmology, Plato gave an account of how the Demiurge formed the celestial bodies. He
blended the three ingredients of the World Soul — Sameness, Difference and Existence —
into a kind of malleable
12
substance, took a strip of it, bent it at some point and marked out sections
measured by the numbers forming the first four terms of the two geometric series 1, 2, 4, 8,
16,… and 1, 3, 9, 27, 81, … . This became known as Plato’s Lambda because of its resemblance to
Λ, the Greek letter lambda (Fig. 10). The powers of 2 and 3 are, however, but two sides of a tetractys
array of integers, the three extra integers shown in blue in Fig. 10 being created by the rule of multiplication of 2 and 3 along
diagonal rows of numbers. This ‘Lambda Tetractys’ and its extrapolation by the Pythagorean
mathematician Nichomachus of Gerasa (c. 60 C.E. – c. 120 C.E.), using more terms in the
two geometric series, was known to generate the tone ratios of the Pythagorean musical scale
as ratios of these numbers. It was thought, however, to have no significance beyond this
musical context. Articles 11^{2} & 12^{3} discussed deeper aspects of this pattern of numbers and their
generalisation, whilst subsequent articles have shown that it plays a fundamental role in
defining the properties of any holistic system that conforms to the divine
archetype or universal paradigm, the seven musical scales being just one example.
The sum of the ten integers is 90, the sum of the integers at the corners of
the tetractys is 36, the sum of the seven remaining integers at the centre and
six corners of a hexagon the red, dotted boundary in Fig. 10) is 54, the sum of the six integers at these corners being
48. That the Lambda Tetractys has 90 as its sum immediately suggests a
connection with the seven octaves of the seven musical scales, for they have 91 intervals up
to 128, i.e., 90 intervals up to its predecessor, the seventh octave of note B with tone
ratio 243/2, which is the 49th Pythagorean note. The following properties
confirm this suggestion: the 90 intervals below the seventh octave with tone ratio 128
comprise 20 overtones, 28 fractional, Pythagorean notes (that is,
(20+28=48) Pythagorean intervals) and 42 nonPythagorean intervals, all
with fractional tone ratios. The latter consist of the 6 nonPythagorean intervals below the
first octave and the 36 nonPythagorean notes of higher octaves. Compare
these numbers with the three main groupings of numbers belonging to the Lambda
Tetractys:
where ‘6’ = 6 nonPythagorean intervals in the first octave,
‘36’ = nonPythagorean intervals of higher octaves and ‘48’ =
Pythagorean intervals. We see that the numbers of Pythagorean and nonPythagorean intervals
below the seventh octave conform to the archetypal pattern of the Lambda Tetractys. As this
defines holistic systems, it must be concluded that the 90 notes between the tonic of the first
octave and the seventh octave constitute a holistic system.^{4}
24 is the 60th interval and the 10th overtone. Below it are
50 fractional intervals made up of 22 Pythagorean intervals and 28
nonPythagorean intervals. 50 is the sum of the triangular array of six
integers in the Lambda Tetractys with 8 at one corner:
Six Pythagorean intervals symbolised by the central number 6 belong to the
first octave. Hence, (22–6=16) fractional Pythagorean intervals belong to higher octaves. This
is the
13
sum of the integers 12 and 4. The other integers 2, 8 and 18 in the
triangular array add up to 28 and signify the number of nonPythagorean integers. There are 10
overtones up to the tone ratio 24. This is the sum of the integers 1 denoting the tone ratio 24
itself) and 9. Above it are 30 intervals below the tone ratio 128. This is the sum of 3 and 27.
Different sets of integers belonging to the Lambda Tetractys therefore add up to the numbers of
Pythagorean and nonPythagorean intervals below the seventh octave.
That the Lambda Tetractys describes so many aspects of the intervallic
composition of seven octaves of the 14 basic notes cannot be coincidental. Instead, it shows
that they constitute a holistic, or Tree of Life, system. Moreover, the Lambda Tetractys
clearly flags the tenth overtone 24, just as we saw both the outer and inner Trees of Life
did.
5. The seven
octaves & the seven 3tuples of octonions
The integers 1, 2, 4 & 8 forming one side of the Lambda Tetractys are the dimensions of the
four only classes of numbers that have division algebras: real numbers, complex numbers,
quaternions and octonions (also called ‘Cayley numbers’). An octonion has the form:
N = a_{0}e_{0} + a_{1}e_{1} +
a_{2}e_{2} + …. + a_{7}e_{7},
where the a_{i} (i = 07) are real numbers, e_{0} is the
identity element 1 and the seven unit octonions e_{i} (i = 17) are imaginary numbers:
e_{i}^{2} = 1. Their multiplication is anticommutative:
e_{i}e_{j} =  e_{j}e_{i} (i≠j)
nonassociative:
e_{i}(e_{j}e_{k})
≠(e_{i}e_{j})e_{k}
and follows the rule
e_{i}e_{i+1} = e_{i+3}.
Every unit imaginary octonion has an inverse, or conjugate, e_{i}* =
e_{i}, where e_{i}e_{i}* = 1.
Similarly, the conjugate of an octonion N is N*, where
N* = a_{0}  a_{1}e_{1}  a_{2}e_{2}
 …  a_{7}e_{7}.
The norm of an octonion is ││N││= √N*N, where
││N││^{2} = a_{0}^{2} + a_{1}^{2} +
a_{2}^{2} + … + a_{7}^{2}.
The inverse of N is N^{–1} ≡ N*/││N││^{2}, so that
N^{–1}N = NN^{–1} = 1. It was shown in Article 28 that there are 13 classes of
real, linear combinations of two or more unit imaginary octonions. This means that there are 13
classes of their inverses. Their polyhedral counterparts are the 13 Archimedean solids and
their duals — the 13 Catalan solids. Their musical counterparts are the 13 different intervals
above the tonic found in the notes of the seven musical scales. This section will explore
further the analogy between the scales and the multiplicative properties of the unit imaginary
octonions.
Raising a note with tone ratio p by an interval m and then raising it by its
complementary interval n (mn = 2) creates the note pmn = 2p, which is the same as the original
note, only one octave higher. The second operation is in this sense the inverse of the first
because it reverts the note to the same kind of note that it was originally, only an octave
higher. Therefore, the complement of a note is the musical counterpart of the inverse of a unit
imaginary octonion. Just as the seven imaginary octonions e_{i} have seven inverses
e_{i}^{1}= e_{i}* = e_{i}, so the 14 different notes of the
seven scales are divided into seven notes and their complements:
14

(As previously done for their tone ratios, Pythagorean notes are written in
black and nonPythagorean notes are written in red).
The Fano plane (Fig. 11) is a useful way of representing the nonassociative and
noncommutative multiplication of the seven unit imaginary octonions.
In mathematics, a projective plane consists of a set of “lines” and a set of
“points” with the following properties:
Given any two distinct points, there is
exactly one line incident with both of them.
Given any two distinct lines, there is
exactly one point incident with both of them.
There are four points such that no line is
incident with more than two of them.
The last condition simply excludes some
degenerate cases.
A projective plane is an abstract mathematical concept, so the "lines" need
not be anything resembling ordinary lines, nor need the "points" resemble ordinary points. It
can be shown that a projective plane has the same number of lines as it has points. This number
can be infinite (as for the real projective plane) or finite. A finite projective plane has
(n^{2}+n+1) points, where n is an integer called the order of the projective
plane.
15
A projective plane of order n has (n+1) points on every line, and (n+1)
lines passing through every point. For all known finite projective planes, the order is a prime
power. The smallest possible projective plane has only seven points and their duals — seven
lines. This is the Fano Plane. It has order 2 because 2^{2} + 2 + 1 = 7.
Each line in the Fano plane joins three octonions that form a 3tuple
(e_{i}, e_{i+1}, e_{i+3}), where the index is defined modulo 7. The
seven 3tuples are:
(e_{1}, e_{2}, e_{4})
(e_{2}, e_{3}, e_{5})
(e_{3}, e_{4}, e_{6})
(e_{4}, e_{5}, e_{7})
(e_{5}, e_{6}, e_{1})
(e_{6}, e_{7}, e_{2})
(e_{7}, e_{1}, e_{3})
They can be represented by seven triangles whose vertices are the vertices
of a heptagon (Fig. 12). Table 4 displays the multiplication of pairs of octonions. For each 3tuple,
there are seven combinations of one, two or three unit octonions:
e_{i}, e_{i+1}, e_{i+3}
e_{i}e_{i+1}, e_{i+1}e_{i+3},
e_{i+3}e_{i} (6 permutations)
e_{i}e_{i+1}e_{i+3} (6 permutations)
Each 3tuple has 12 permutations of two or three imaginary octonions.
Similarly, as e_{i}e_{i+1} = e_{i+3} = e_{i+1}e_{i} =
(e_{i+1})(e_{i}) = e_{i+1}^{–1}e_{i}^{–1},
then e_{i+1}^{–1}e_{i}^{–1} = e_{i+3} =
e_{i+3}^{–1}, that is, the inverses of the octonions in a 3tuple also form a
3tuple with 12 permutations of pairs or triplets. Their multiplication is represented by the
Fano plane with each e_{i} replaced by e_{i}^{–1} and with the
directions of all arrows reversed to take account of the reverse ordering of. The seven
octonions therefore have (7×12=84) permutations, as do their inverses. The seven 3tuples and
their inverses display (84+84=168) permutations of their members. The octonion
algebra can be represented by the Fano plane because SL(3,2), the simple group of automorphisms
(incidencepreserving bijections) of
the latter, is of dimension 168. The significant
factorisation of 168 is 7×24, where 24 is the sum of the number of
permutations of two or three octonions and the number of permutations of their inverses. We
shall discuss in Section 8 how this factorisation manifests in one of the most beautiful and
important objects in mathematics — the Klein Configuration.
In each of the seven 3tuples, there are seven permutations of the seven
octonions taken one at a time, 42 permutations of them taken two at a time and 42 permutations
taken three at a time. They are shown in Table 5:
16
Table 5. Permutations of the unit imaginary octonions in each 3tuple.
The permutations of single octonions create three sets of seven octonions,
the permutations of two octonions create three sets and three sets of their negatives and the
permutations of three octonions create three sets of seven ‘1’s and three sets of seven ‘1’s.
The 84 permutations of two or three octonions consist of 42 positive numbers
(21 octonions, 21 ‘1’s) and 42
negative numbers (21 octonions, 21 ‘1’s).
Similarly for the 84 permutations of two or three inverse unit octonions. Hence, the seven
3tuples and their inverses have 84 positive numbers and 84 negative numbers as
permutations.
The real unit octonion corresponds to the tonic of a scale, the seven unit
imaginary octonions correspond to the seven octaves and the 84 permutations of two or three
octonions correspond to the 84 other intervals up to the seventh octave. Each 3tuple
corresponds to an octave of the set of 12 different notes between the tonic and octave of the
seven musical scales.
Divided into tetractyses, a heptagon contains 42 yods surrounding its centre
(Fig. 13). Each sector signifies a musical scale, the six yods per tetractys
sector symbolizing the six notes above the tonic in each one. In the context of octonions,
the central yod denotes ‘1’, the real unit octonion, each sector symbolizes a 3tuple and
the six yods symbolize the three octonions and their three pairings. With each sector
divided into
17
18
three tetractyses, the centre of a heptagon is surrounded by 105
yods,^{1} or 15 yods per sector (Fig. 14). The three octonions in each 3tuple form three combinations of one
octonion (denoted by the coloured yods), three combinations of two octonions with six
permutations (denoted by the black yods) and one combination of three octonion with six
permutations (denoted by the white yods). In other words, the seven different combinations
for each 3tuple (e_{i}, e_{i+1}, e_{i+3}) generate
15 permutations if we regard each octonion in it (say, e_{i}) as
1×e_{i} = e_{i}×1. The seven 3tuples therefore possess
(7×15=105) permutations. Each yod symbolizes a permutation, the central yod
denoting the real unit octonion. The three combinations of one octonion are symbolized by
the yods at the centres of the three tetractyses in each sector. The six black yods on the
edges of the sector and at its centre denote the six permutations of pairs of octonions
and the six white yods on the edges of the tetractyses inside the
heptagon symbolize the six permutations of the three octonions in a 3tuple.
Fourteen octonions are just copies of the basic set of seven octonions, so
that there are 91 distinct permutations of the octonions in the seven 3tuples. The 13
such permutations per sector correspond to the 13 tone intervals in each octave of the notes
belonging to the seven musical scales. As they comprise six Pythagorean intervals, six
nonPythagorean intervals and the octave, we find the following correspondences:
Single octonion


octave note

Six permutations of two octonions


six Pythagorean intervals

Six permutations of three octonions


six nonPythagorean intervals

3tuple


one octave

Just as the fourth class of 8dimensional numbers constitute a holistic
system with 91 distinct permutations of their, so, too, the 91 intervals in seven octaves of
the notes belonging to the seven musical scales make up a holistic system. The identity element
1 corresponds to the first note of the first octave.
A heptagon whose sectors are each divided into three tetractyses has 91
hexagonal yods (Fig. 15). The 13 intervals per octave can be assigned to the 13 hexagonal
yods per sector. Alternatively, the 14 notes in the seven scales can be assigned to its
corners

three tetractyses has (15n+1) yods.
19
and to the centres of its sectors, with the 21 yods at
centres of tetractyses symbolizing the 21 overtones up to 128, the 28 other
yods on edges of sectors symbolizing the 28 Pythagorean intervals and the 42 yods on edges of
tetractyses inside the heptagon denoting the 42 nonPythagorean intervals. The intervals of the
seven musical scales are reproduced in the Pythagorean geometry of the heptagon.
6. Comparison
with the disdyakis triacontahedron
There are (10+22=32) Pythagorean intervals and 28 nonPythagorean intervals up to the note with
tone ratio 24. Compare this with the 60 vertices surrounding the AA axis of the disdyakis
triacontahedron, of which 32 are either B or C vertices and 28 are A vertices (Fig. 16). It is as if the 60 vertices surrounding its AA axis symbolize the
60 intervals up to 24, the A vertices symbolizing the nonPythagorean intervals and the B
and C vertices symbolizing the Pythagorean intervals. The B vertices cannot symbolize just
the overtones themselves because there are 10 overtones but 12 B vertices. Similarly, there
are 22 fractional Pythagorean intervals but only 20 C vertices. The BB axis would allow the
10 B vertices surrounding it to correspond to the 10 overtones, but there would be two few C
vertices to correspond to the 22 Pythagorean intervals and two too many A vertices to
correspond to the 28 nonPythagorean intervals. The CC axis surrounded by 18 C vertices, 12
B vertices and 30 A vertices does not permit any obvious correspondence. Hence, only the AA
axis generates a correlation between the surrounding types of vertices and the numbers of
Pythagorean and nonPythagorean intervals up to 24. It indicates that the rhombic
triacontahedron with 32 vertices, which underlies the disdyakis triacontahedron, is what is
significant here, not the fact that the former is a compound polyhedron formed by joining
the vertices of the dodecahedron and icosahedron. It is further evidence of the special
significance of the tenth overtone. Previous articles^{5}
proved that the disdyakis triacontahedron is the polyhedral version of the
inner (polygonal) Tree of Life. In particular, it was shown in Article 27 that it has 1680
vertices, edges and triangles surrounding an AA axis when its interior triangles are each
divided into three tetractyses and its triangular faces each turned into a single
tetractys.^{6} This is the structural parameter of the
E_{8}×E_{8} heterotic superstring, being the number of circularly polarized
oscillations in each of the ten closed curves making up this type of superstring (see
Fig. 25). That fact that the 60 vertices surrounding the axis create 1680
geometrical elements and symbolize the 60 intervals up to the tenth overtone suggests that
the former is connected to the number 24 in some way. It is also significant that the fourth
type of polygon in the seven layers of vertices of the disdyakis triacontahedron — the
polygon forming its equatorial plane — is a 12sided polygon with 12 corners and 12 edges on
its boundary, i.e., 24 geometrical elements. Once again, the arrangement of the vertices of
the disdyakis triacontahedron reveals the presence of the number 24. Is the Pythagorean
mathematics of music therefore intrinsic to the physics of the vibrations of
superstrings?
Here is further evidence that it is: Article 16^{7} showed that the seven musical scales
20
have 84 rising intervals between their notes that repeat the basic set of
seven intervals of the Pythagorean scale. They also have 84 falling intervals. The number of
rising and falling Pythagorean intervals varies from scale to scale:
C scale

D scale

E scale

F scale

G scale

A scale

B scale

2×13=26

2×12=24

2×13=26

2×12=24

2×11=22

2×11=22

2×12=24

Total = 2×84 = 168.

Average = 168/7 = 24.

However, the average number of rising and falling Pythagorean intervals per
scale is 24. Once more, we find the number 24 characterising the seven musical scales! In the
context of the tetrahedral generalisation of the Lambda Tetractys discussed in Articles 11 and
12, the number that replaces the number 6 at its centre is 24. As discussed earlier, the
products of two and three octonions in a 3tuple have 12 permutations, their inverses having 12
permutations as well. Therefore, a 3tuple of octonions and a 3tuple of their inverses have 24
permutations of two and three octonions. Finally, given that the ancient Greeks regarded the
eight notes in a scale as two groups of four notes, or tetrachords, it is remarkable that the
number of broken chords of four notes that can be played with eight notes is
^{8}P_{4} = ^{8}C_{4}×4! = 1680, the superstring structural
parameter.
As well as being the number of yods surrounding the centre of a 2ndorder
tetractys and the number of notes other than octaves in the seven octaves of notes in the seven
musical scales, the number 84 is the number of permutations of 1, 2, 3 and 4 objects arranged
in a tetractys:
They have 26 combinations, the last row having
15 combinations, which shows how the Godnames YAHWEH with number value
26 and YAH with number value 15 prescribe the Pythagorean
representation of holistic systems. It illustrates how the number 84 characterises holistic
systems like the seven musical scales and the seven 3tuples of octonions. The 84 permutations
comprise (1!+2!+3!+4!=33) permutations of all the objects in each row, i.e., 32
permutations of sets of two, three and four objects, 10 permutations of single objects and 42
permutations of two and three objects. The 84 permutations therefore naturally divide into
(10+32=42) permutations of single objects and all objects in a row and 42 permutations of two
and three objects. The counterparts of this 42:42 division of permutations in the seven octaves
are the 42 Pythagorean notes other than octaves and the 42 nonPythagorean notes below the
seventh octave.
Counting from the tonic of the first octave, the tone ratio 24 (=1×2×3×4) is
the 33rd Pythagorean note (33=1!+2!+3!+4!) and the perfect 5th of the fifth octave. Starting
from this note, the 33rd note is 576 = 24^{2}and still the perfect 5th of the new fifth
octave. This is the 65th note from the tonic of the first octave, where
65 is the 33rd odd integer.
21
The Godname ADONAI with number value 65 prescribes sequences
of 33 Pythagorean notes whose last note has a tone ratio always 24 times that of the first
one. Only the first sequence (1) has ten overtones. The second sequence (2) has 24
overtones in addition to the first overtone with tone ratio of 24. In general, the nth
sequence terminates in the note with tone ratio 24^{n}. Notice that the Godname of
Netzach, the fourth Sephirah of Construction, with number value
129, determines the end of the fourth sequence with tone ratio
24^{4}, that is, 4! raised to the fourth power. This illustrates the
Tetrad Principle^{8} at work. Indeed, as 24 = 5^{2} – 1 = 3 + 5 + 7 + 9, 24 is
the sum of the first four odd integers after 1. Furthermore, starting from a point,
24 more yods are needed to construct a square, symbol of the number 4, from tetractyses
(Fig. 17). The central yod denotes the octave, the 12 yods inside the square
denote the 12 intervals below the octave and the 12 yods on its boundary denote the 12
intervals between the 13 notes of the octave above the tonic. The square represents
all the notes in the seven musical scales and the intervals between them.
Given that the note with tone ratio 24 is the 61st note, it is a remarkable
illustration of the power of the Tetrad Principle to define numbers of scientific
significance (as the number 24 will prove to be) that there are 61 yods in a square whose
sectors are divided into three tetractyses (Fig. 18). The central, white yod symbolizes the tonic, the 32 black yods on
the sides and diagonals and at centres of tetractyses denote the 32 Pythagorean intervals up
to tone ratio 24 and the 28 red yods on the internal edges of tetractyses denote the 28
fractional, nonPythagorean intervals up to this note.
That the number 33 truly measures holistic cycles is demonstrated
par excellence in the inner form of the Tree of Life. Its seven enfolded polygons
(Fig. 19) have 36 corners i.e., 34 corners outside their
shared edge. In any set of overlapping Trees of Life, a set
22
of these polygons are enfolded in each tree. The corners of polygons
enfolded in successive Trees of Life touch at only one point, namely, the topmost corner of the
hexagon coincides with the lowest corner of the hexagon enfolded in the next higher tree. There
are n sets of seven polygons enfolded in n trees with (33n+1) corners outside their root edges.
There are therefore 33 corners per tree outside their shared edge. The 70 polygons enfolded in
the lowest ten Trees of Life have 351 corners. This is the number value of
Ashim, the Order of Angels assigned to Malkuth (see Table 1).
When Trees of Life overlap, all Sephirah except Chesed and Geburah are
shared by adjacent trees. Defining a ‘tree level’ as a horizontal striation of one or two such
Sephiroth, the lowest Tree of Life has seven tree levels and ten overlapping trees have 33 tree
levels (Fig. 20). As ten overlapping Trees of Life are the Tree of Life
representation of the ten Sephiroth, it demonstrates that the number 33 is a parameter of a
holistic system.
The number of yods in the lowest n overlapping Trees of Life when all their
triangles are turned into tetractyses can be shown^{9} to be:
Y(n) = 50n + 30.
As Y(n+1) – Y(n) = 50, the Godname ELOHIM with number value
50 determines the increase in number of yods with successive trees. The number
of yods in the lowest 33 trees is Y(33) = 1680. This connects the superstring structural
parameter 1680 to the number 33. The 91 subplanes in the seven cosmic planes can each be
represented by a Tree of Life. Assigning each successive Pythagorean note in the seven octaves
to a tree, the lowest 49 trees mapping the cosmic physical plane are
correlated with the 49 Pythagorean notes above the tonic, whilst the next 42
trees correlate with the 42 nonPythagorean notes. As the 33rd note, the tenth overtone 24 is
assigned to the 33rd tree. This indicates a connection between at least the number 24
and the superstring structural parameter 1680, if not this number as a musical tone ratio as
well. The number of yods in the lowest 49 trees is Y(49) =
2480, i.e., the number of yods in 248
23
tetractyses. 248 is the dimension of the superstring
symmetry group E_{8} and 2480 is the number of spacetime components of the
248 10dimensional gauge fields of E_{8}. Therefore, the tenth
overtone determines the number defining the structure of the superstring and the
number of Pythagorean notes in the seven octaves determines the nature of the unified
superstring force — a very remarkable conclusion.
As 1680 = 70×24 and as the Tree of Life contains 70 yods when its triangles
are turned into tetractyses (see Fig. 4), it can be regarded as embodying the number 1680 when the number 24
is assigned to each yod. It further demonstrates the significance of this number for the
physics of superstrings.

7. The dodecagon defines all intervals in the seven
octaves The tetractysdivided hexagon with 91 yods was shown in
Section 2 to embody the 91 intervals in seven octaves of the set of 14 different notes
that make up the seven musical scales. There are 90 intervals between the 91 notes above
the tonic of the first octave. (91+90=181) intervals can therefore be defined either
between this note and all the other notes or between successive notes. This fact is
symbolized by the 181 yods in the dodecagon — the last of the regular polygons forming
the inner Tree of Life — when its sectors are divided into three tetractyses
(Fig. 21). The six
Pythagorean notes between the tonic and the first octave can be assigned to
alternating corners of the dodecagon, with the red yod at the centre of six sectors denoting
the six non Pythagorean intervals. The 48 intervals above the first octave up
to the tenth overtone with tone ratio 24 are denoted by orange yods arranged in pairs on edges
of tetractyses inside the dodecagon. The 30 intervals above the tenth overtone up to the
penultimate note of the seventh octave are denoted by the 30 green yods lying on radial edges
or at centres of tetractyses. The 90 intervals between successive notes are symbolized by
the 90 yellow yods in alternating sectors. Finally, the yod at the centre of the dodecagon
denotes the seventh octave. There are (48+30=78) intervals from the
first octave to the seventh octave and 90 intervals between successive notes
in the seven octaves, starting from the second note. There are therefore 168
intervals other than the basic set of 12 intervals below the first octave and the seventh
octave. Quite apart from it being the number of permutations of two and three octonions
belonging to the seven 3tuples and of their inverses, this reproduces the number values of the
two Hebrew words ‘Cholem’ and ‘Yesodoth’ in the name of the Mundane Chakra of Malkuth, which
has the number value 168 (Fig. 22). This is a very remarkable illustration of how the gematria number
values of the Godnames, Archangelic Names, etc listed in Table 1 quantify aspects of a holistic system like the seven octaves of the
notes belonging to the seven musical scales.
As 13^{2} – 1 = 168 = 3 + 5 + 7 + … + 25, the
number 168 is the sum of the 12 odd integers after 1 that can be assigned to
the 12 corners of a dodecagon (Fig. 23). The dodecagon therefore embodies this number both arithmetically
and geometrically. The pair
25
of joined dodecagons embodies the superstring structural parameter 1680 in a
way that directly connects this fundamental number to the number 24. A 2ndorder tetractys has
85 yods (see Fig. 8). As there are 13 yods along each side, there are 72
yods per sector. Hence, a dodecagon has, including its centre, (12×72 + 1 =
865) yods. (865–13=852) yods are outside the edge one dodecagon shares with the other.
(852–12=840) yods outside this edge surround the centres of the 12 2ndorder
tetractyses. The pair of dodecagons has(840+840=1680) such yods surrounding these 24
centres (Fig. 24). The 840 yods in each dodecagon correspond to the 840 vertices,
edges and triangles needed to construct each half of the disdyakis triacontahedron from
triangles.
26
This is a remarkable example of the power of the sacred geometry of the Tree
of Life to represent numbers of scientific significance. Several previous articles has proposed
that along each of the ten curves comprising the E_{8}×E_{8} heterotic
superstring are spread 24 gauge charges of E_{8} associated with its nonzero roots, so
that all ten curves carry the gauge charges associated with its 240 nonzero roots. Each
2ndorder tetractys in the two dodecagons would then represent an E_{8} gauge charge.
The heterotic superstring has waves that travel clockwise in 10dimensional spacetime mixed
with waves that travel anticlockwise in 26dimensional spacetime. A string in
the latter spacetime can oscillate in 24 transverse directions. The 24 vibrational degrees of
freedom of the closed curves making up the superstring manifest in the Tree of Life blueprint
as the 24 sectors of the two dodecagons. The heterotic superstring described by Annie Besant
and C.W. Leadbeater^{10} with the use of a yogic siddhi called ‘anima’
consists of a set of ten closed curves (Fig. 25). Each revolves 2½ times in an outer spiral, making 840 circularly
polarised oscillations as it twists down to its lowest point. It
then revolves 2½ times in a narrower helix towards the starting point at the
top, making 840 more oscillations. This separation of its form into an outer half and an inner
half corresponds in the polygonal form of the Tree of Life to the pair of similar dodecagons,
each containing outside their shared edge 840 yods that surround the centres of their sectors.
In its polyhedral form, it corresponds to the 840 vertices, edges and triangles in each half of
the disdyakis triacontahedron, half of it being the mirror image of the other half.
As further evidence that the seven octaves constitute a Tree of Life
pattern, Fig. 26 shows the 194 yods associated with a set of the first six enfolded
polygons. These form a Tree of Life pattern prescribed by Godnames. For example, the Godname
YAHWEH with number value 26 prescribes their 26 corners,
whilst the Godname ELOHIM with number value 50 prescribes the
50 corners of both sets of polygons (for details of how the other Godnames
prescribes them, see Article 4^{11}). When their sectors are turned into tetractyses,
168 yods need to be added to the 24 yods at their corners. Of these, 78
yods are in the triangle, pentagon and octagon, and 90 yods are in the square, hexagon and
decagon. Once again, we see that the number 24 is associated with the number
168. It is as if, as more basic degrees of freedom, the former generates
the latter as new variables. In the context of superstrings, there are 240 roots of
the gauge
27
symmetry group E_{8} and eight simple roots. Arranging this number
as a tetractys array of the number 24,
There are 72 nonzero roots of its exceptional subgroup
E_{6} and 168 roots of E_{8} that do not belong to
E_{6}. This is the group origin of the number 168. Its factorisation
7×24 is a manifestation of fundamental symmetries whose nature has yet to be determined and
which generate the gauge group E_{8} describing the unified superstring
interaction.
The very same three numbers 24, 78 & 90 define the geometry of the
disdyakis triacontahedron. Surrounding its axis are 1680 corners, edges and triangles, created
when its 180 internal triangles are formed by joining its vertices to its centre and are then
divided into three tetractyses. This is easily seen from the table below:

Grand total =

1680.

There are 780 (=78×10) edges and 900 (=90×10) corners and faces, totalling
1680 (=168×10) geometrical elements. Built from triangles, the geometrical
composition of the disdyakis triacontahedron manifests the number value 168 of
Cholem Yesodoth, the first word expressing the number of edges surrounding its axis
and the second word the number of corners and triangles that surround it.
Let us now compare the geometrical composition of the disdyakis
triacontahedron with the interval composition of seven octaves. The 780 edges correspond
to the 78 intervals from the first octave to the last note before the seventh octave and
the 900 vertices and triangles correspond to the 90 intervals between successive notes
from the second octave up to the seventh octave. We pointed out in Section 6 that the 60
vertices surrounding the axis symbolise the 60 intervals up the tenth overtone. As there
are 30 intervals beyond it to the last note before the seventh octave and 90 intervals
between successive notes, (30+90=120) intervals correspond to the 120 faces of the
disdyakis triacontahedron. Its 180 edges can alone be thought to symbolize the 90
intervals between the tonic and the last note before the seventh octave and the 90
intervals between successive notes, starting with the first note after the tonic. The
90:90 division reflects the inversion symmetry of the disdyakis triacontahedron, every
edge having its mirror image. The 12 edges between the 12 vertices in its equatorial plane
correspond to the 12 intervals below the first octave and the remaining
168 edges correspond to the 168 notes and intervals
between notes from the first octave up to the seventh octave. Music is number experienced
in time. The geometry of the disdyakis triacontahedron manifests in space the holistic
pattern of seven octaves of
28
the seven musical scales. It expresses all possible intervals between these
scales.
8. The 24 heptagons of the Klein
Configuration In 1878, the great mathematician Felix Klein, known as
one of the nineteenth century’s finest geometers and to students of mathematics as the
discoverer of the onesided, closed surface called the “Klein bottle," discovered that
the quartic equation:
x^{3}y + y^{3}z + z^{3}x = 0
has the 336fold symmetry of the group SL(2,7). This curve is known to
mathematicians as the “Klein quartic.” Its Riemann surface is mapped onto itself by
168 analytic transformations (automorphisms). Curves of genus g that display
the maximum number of automorphisms 84(g–1) and the same number of antiautomorphisms are
known as Hurwitz curves.^{12} As 168 = 84×2, the
Klein quartic is a Hurwitz curve mapped onto a surface of genus 3, i.e., the
3torus (Fig. 27). If triangles are joined together so that three of them meet at a
corner, a tetrahedron is formed. If squares are joined so that three meet at a corner, a
cube results. Pentagons can be joined to form a dodecahedron. However, hexagons cannot be
joined to form a Platonic solid. Instead, they form a tiled
29
plane looking like honeycombs. If heptagons are joined so that three meet at
a corner, the tiling can be done only on a hyperbolic surface with negative curvature because
the sum of the angles of the three corners of a heptagon is now greater than 360 degrees.
Tessellations are represented by the Schläfli symbol {p,q}, which means that q regular polygons
with p vertices surround each vertex. Fig. 28 displays the {3,7} tessellation with 56 triangles. Its socalled
‘Poincaré dual’ is the {7,3} with 24 heptagons. The rings of heptagons around the central
one in Fig. 26 appear smaller but that is just the distortion created by their
being drawn on the hyperbolic surface. The tessellation of the Riemann surface of the Klein
quartic can be done only on the 3torus. However, not any number of heptagons can be cut out
and wrapped around the 3torus. Only 24 heptagons can be. They are shown in Fig. 28 with their hyperbolic triangular sectors in different colours. The
seven sectors are made up of two different slices, each with 12 triangles. There are 84
triangles in seven slices made up of 28 red, 28 yellow and 28 green triangles. The seven
slices of the other type have 84 triangles made up of 21 yellow,
21 green, 21 red and 21 cyan triangles.
The 168 symmetries of the Klein quartic arise from the sevenfold symmetry
of the Klein Configuration, the 12 rotational symmetries of the tetrahedron into which it
can be deformed and the 12 reflection symmetries of the latter. Here is an explicit meaning
of the number 24: the order of the tetrahedral (and cubic) symmetry group.
The 168 automorphisms of the Klein quartic represented by
the 168 triangles of the Klein Configuration manifest in the disdyakis
triacontahedron as follows: Article 34 proved^{13} that the regular counterparts in the inner Tree of Life of the
8sided, 10sided, 6sided and 12sided polygons formed by the 36 vertices
in one half of this polyhedron have 168 yods on their edges outside their
shared edge (Fig. 29). The octagon and decagon have 84 such yods, as do the hexagon and
dodecagon. This reveals the character of the number 168 as the parameter
defining the shape of a
Tree of Life pattern for these yods delineate the shapes of the four
polygons. The polyhedron has 180 edges, of which 12 edges of the fourth polygon shape its
equatorial plane, leaving 168 edges, of which 84 edges are above the plane and
84 edges below it. The counterpart of this geometry in the polygonal form of the inner Tree of
Life is the fact that, the first four polygons in each half of it have 84 yods outside the
shared edge other than centres of polygons or yods that are shared with the outer Tree of Life
(Fig. 30).
30
31
Musically speaking, the 12 centres or shared yods of the first (4+4)
polygons and the 12 edges of the disdyakis triacontahedron symbolise the 12 different notes in
the seven musical scales between the tonic and the octave, whilst the (84+84) yods or edges
denote the 84 rising intervals and the 84 falling intervals between their notes.^{14}
The number 24 plays a fundamental role in the I Ching table (Fig. 31) as the number of lines and broken lines in the eight basic
trigrams. There are 28 hexagrams above the diagonal row of eight hexagrams shown in red.
They comprise 56 trigrams with (56×3=168) lines and broken lines. They
correspond to the 56 hyperbolic triangles, each with three vertices, of the {3,7} tiling of
the Riemann
surface of the Klein quartic onto a 3torus. The 56 offdiagonal trigrams
with 168 lines and broken lines below the diagonal of the table correspond to
the 168 antiautomorphisms of the Klein quartic.
Just as the tone ratio 24 is the 61st note in the ascending sequence of
notes in the seven musical scales, so the tone ratio 384 is the 61st Pythagorean note
(Fig. 32). What is remarkable is that 384 is the number of lines and broken
lines in the 64 hexagrams of the I Ching table, which are all possible
pairings of the eight trigrams with 24 lines and broken lines! This is not coincidental. Nor
is it coincidental that there are 128 trigrams, where 128 is the seventh octave completing a
holistic system of the notes of the seven musical scales.
In I Ching, the lines are socalled ‘stable Yang
32
lines’ and the broken lines are ‘stable Yin lines.’ If we suppose that Yang
lines represent different phases of an oscillation with a positive amplitude and that Yin
broken lines represent phases that differ by180 degrees from the former, then the
168 lines and 168 broken lines belonging to offdiagonal
hexagrams of the I Ching table represent a system of 24 oscillators, each with seven different
positive phases and seven different negative phases. The lines and broken lines of the diagonal
hexagrams represent oscillators in a state of zero amplitude with all their phases cancelled
out. Each trigram appears seven times in the set of 56 trigrams above or below the diagonal,
that is 14 times altogether. As shown in Article,^{15} the I Ching table is isomorphic to the Klein Configuration, the
168 lines corresponding to the 168 automorphisms of the
Klein quartic and the 168 broken lines corresponding to its
168 antiautomorphisms. The 56 trigrams correspond to the 56 triangles in
the {3,7} tiling. The 24 lines and broken lines in the eight trigrams correspond to the 24
triangles in each of the seven sectors in the {7,3} tiling of the Klein Configuration, their
14 (2×7)fold repetition corresponding to its 14 halfsectors. The pairing of trigrams in a
hexagram corresponds to the two halves of each sector.
It was shown in Article 21^{16} that the I Ching table is also isomorphic to a 3×3×3 array of
cubes. The proof is summarized here: a face of a cube can point along the positive or
negative directions of the X, Y & Z axes. By replacing the yang line by a positive sign
and the Yin broken line by a negative sign, the eight trigrams:
become ordered sets of three signs, each symbolizing three orthogonal faces
that intersect at the eight corners of a cube (Fig. 33). A hexagram is a permutation of two trigrams and can be represented
by an arrow joining the two corners of the cube defined by its trigrams. As pairs of similar
trigrams, the hexagrams along the diagonal of the I Ching table denote the eight corners. A
point in 3dimensional space such as the corner of a cube is also the corner of seven other
contiguous cubes, three in the same plane as this cube and four above it. This means that
the corner is defined seven times, so to speak, by the three orthogonal faces of seven other
cubes surrounding it. The eight corners of a cube are therefore defined by
(8×7×3=168) faces, 84 of them directed
33
34
in positive directions of the axes and 84 in negative directions. The 24
faces of the cube that define its eight corners are symbolised by the 24 Yang/Yin lines of the
eight upper trigrams in the diagonal hexagrams and the 168 Yang/Yin lines of
the 28 hexagrams above the diagonal symbolize the 168 faces of the seven
adjacent cubes. By then considering a 3×3×3 array of cubes so that each corner of the central
cube is surrounded by seven contiguous cubes, it is simple to show^{17} that there are 168 faces defining the 32
corners of the 26 cubes that lie along the outer edges of the 3×3 array
(Fig. 34). The other 288 faces define the four corners within each face,
which do not form the boundaries of the array. There are
(168+168=336) faces defining those corners that shape
both the central cube and the cubes surrounding it. The 168 faces
defining the former correspond to the 168 automorphisms of the Klein
Configuration, whilst the 168 faces defining the latter correspond to its
168 antiautomorphisms. The 168 Yang/Yin lines above the
diagonal of the I Ching table correspond to the 168 faces defining the
eight corners of the central cube and the 168 lines below the diagonal
correspond to the 168 faces defining the 32 corners lying along the edges
of the array.
In the factorisation 168 = 7×8×3, the number ‘7’ denotes in
the I Ching table the number of copies of each trigram in the offdiagonal hexagrams, in the
Klein Configuration the number of sectors and in the 3×3×3 array the seven other cubes meeting
at the corner of a cube. The number ‘8’ denotes in the table the number of different trigrams,
in the Klein configuration the number of triangles in each sector (see Fig. 28) and in the 3×3×3 array the eight corners of the central cube. The
number ‘3’ denotes in the table the number of lines in each offdiagonal trigram, in the
Klein Configuration the number of halfsectors of each heptagon in each triangle and in the
3×3×3 array the number of orthogonal faces needed to define a point. The I Ching table, the
Klein Configuration and the 3×3×3 array of cubes all display the factor 7 and the factor 24.
These isomorphic objects show that the number 24 determines the number 168.
For the table, it is the number of lines and broken lines in the eight trigrams. For the
Klein Configuration, it is the 24 possible rotations that leave the tetrahedron unchanged,
the 3torus that it can cover being topologically equivalent to a tetrahedron with three
holes bored through it. For the 3×3×3 array, the number 24 signifies the basic set of 24
faces defining the eight corners of the central cube, these being repeated for the seven
cubes contiguous with any given corner. For the octonions represented by the Fano plane with
the sevenfold symmetry of its seven points and seven lines, it is the 12 permutations of
pairs and triplets of octonions in a 3tuple and the 12 permutations of their inverses. For
the seven musical scales, 24 is the number of repeated intervals belonging to the basic set
of 14 notes averaged over the scales. For their seven octaves, it is the number of basic
rising and falling tone intervals in each octave.
Figure 35 shows the equivalence between the inner Tree of Life, the I Ching
table, the Klein Configuration and the disdyakis triacontahedron in representing the
(168+168) formative degrees of freedom of a holistic
system. They manifest in spacetime as the 168 circularly polarised
oscillations made by each of the ten closed curves of the E_{8}×E_{8}
heterotic superstring as it winds 180° about the axis in either an outer or an inner half of
the superstring. Each holistic system exhibits 24 independent, higher order degrees of
freedom that generate 168 structural elements. In the heterotic
superstring, they reflect the 24 transverse modes of vibration of a string in
26dimensional spacetime.

^{4} As the set of 14 notes constituting the seven scales is a holistic set,
it, too, is defined by the Lambda Tetractys. There are (14×13/2 = 91) intervals between
them, that is, 90 intervals other than the octave. This is the sum of the ten numbers of the
Lambda Tetractys. There are six Pythagorean intervals below the first octave. This is
denoted by the number 6 at the centre of the Lambda Tetractys. There are 84 intervals other
than these notes. This is the sum of the nine integers surrounding the central integer.
There are (6×6=36) intervals between the six Pythagorean notes and the six
nonPythagorean notes. This is the sum of the integers 1, 8 and 27 at the corners of the
tetractys. There are (6×5/2=15) intervals between the six Pythagorean notes
and 15 intervals between the six nonPythagorean notes. There are six
intervals between the octave and each set of six notes, making 12 intervals. The number of
intervals other than Pythagorean notes and those between each set of six notes =
15 + 15 + 6 + 6 + 6 = 48. This the sum of
the six integers in the Lambda Tetractys arranged at the corners of a hexagon.

there are (6n+5) yods at corners, two yods between the ends of each edge, i.e., 2E(n) yods,
