Tony Smith said:rntsai asked "how?" is "GF(4) is the Dynkin diagram for the Lie Algebra D_4 = spin(8)".
I might not do as good a job as Lawrence B Crowell would do,
here is my attempt at showing "how?":
The Galois field GF(4) = {0,1,w,w^2}
where
w = (1/2)( - 1 + sqrt(3) i )
and
w^2 = (1/2)( - 1 - sqrt(3) i )
Look at the 0 as the zero or origin as the central dot of the D_4 Dynkin diagram visualized as being in the complex plane centered on the origin
*
\
*--* ( I used two -- to make the length more nearly equal to that of \ and / )

and
look at the 1 as the outer Dynkin dot on the right-hand side
and
look at the w as the upper outer Dynkin dot on the left-had side
and
look at the w^2 as the lower outer Dynkin dot on the left-hand side.

Berlin said:Gets more interesting every day here, and I understand less. If we focus again on Garretts starting point: What is essentially changes in his results? I am wondering if we could just change the E8 root numbers into complex numbers, change 0.5 to 0.5 +i*0.5*sqrt(3) etc. and connect the three generations in this way. Surely very naive. Is it established here that we need three E8's?

CarlB said:With the Koide mass formula, the leptons are supposed to be color singlets built from preons. The "M" operator picks out the individual preons so it is the color operator. It has three eigenstates, the diagonal pure density matrices (i.e. diagonals given by (0,0,1), (0,1,0), or (1,0,0) ). Therefore M is the operator for color, which takes eigenvalues of \exp(2i n \pi/3) for n=0, 1, 2. These eigenvalues are the same eigenvalues of the J operator, naturally, but the J operator is interpreted here as giving the generation number.

rntsai said:This construction works with codes that contain their dual. Self dual
codes (like the Hamming [8,4,4], Golay [24,12,8],...) are obviously covered
I don't know how you constructed the classical code with e8, if it
contains its dual then this will work for it. In my opinion, this
construction is a little restricitive. A lot of good quantum codes
are not constructed this way.
Tony Smith said:James Lepowsky said in math.QA/0706.4072 that "... the Fischer-Griess Monster M ... was constructed by Griess as a symmetry group (of order about 10^54) of a remarkable new commutative but very, very highly nonassociative, seemingly ad-hoc, algebra B of dimension 196,883 ... The Monster is the automorphism group of the smallest nontrival string theory that nature allows ... Bosonic 26-dimensional space-time ... "compactified" on 24 dimensions, using the orbifold construction ...".
Tony Smith said:My E6 string model CERN CDS preprint EXT-2004-031 on the web at
http://cdsweb.cern.ch/record/730325
is also based on orbifolding bosonic 26-dim string theory,
with strings physically interpreted as world-lines,
and with 8-dim Kaluza-Klein spacetime based on 8-dim branes with E8 structure.
Tony Smith said:In that model, a Single Cell can be described by
taking the quotient of its 24-dimensional O+, O-, Ov subspace
modulo the 24-dimensional Leech lattice,
and
its automorphism group is the largest finite sporadic group, the Monster Group, whose order is
808017424794512875886459904961710757005754368000000000
=
2^46 x 3^20 x 5^9 x 7^6 x 11^2 x 13^3 x 17 x 19 x 23 x 29 x 31 x 41 x 47 x 59 x 71
or about 8 x 10^53.
Tony Smith said:The Mpl part of M may be related to Aut(Leech Lattice) = double cover of Co1.
The order of Co1 is 2^21.3^9.5^4.7^2.11.13.23 or about 4 x 10^18.
The Mw part of M may be related to Aut(Golay Code) = M24.
The order of M24 is 2^10.3^3.5.7.11.23 or about 2.4 x 10^8.
If you look at the physically realistic superposition of 8 such Cells,
you get 8 copies of the Monster of total order about 6.4 x 10^54,
which is roughly the product of the Planck mass and Higgs VEV squared:
(1.22 x 10^22 )^2 x (2.5 x 10^5)^2 = 9 x 10^54
The full physics of that model can be regarded as an infinite-dimensional Affinization of the Theory of that Single Cell.

CarlB said:A basic problem with assuming an MUB model for elementary particles is that it implies 2 body interactions between states. If two states are in the same basis, the transition probability between them is zero, and if they're in different bases, the transition probability is 1/d. Unfortunately, the standard model is built with 3 body interactions.
Tony Smith said:Lawrence B. Crowell said "... 196560 ... is "close" to the 196884 ... but some where an additional 324 ... elements creep into the picture ...".
The Leech lattice has
3x240 + 3x16x240 + 3x16x16x240 =
= 720 + 11,520 + 184,320 = 196,560 units.
The 196,560 Leech lattice units,
plus 300 = symmetric part of 24x24,
plus 24
produce the 196,884
that is the dimension of a representation space of the Monster.

Mark A Thomas said:The monster symmetries generates a D3/D7 quantum cosmology utilizing a gauge theory having one to one correspondence with the cosmological rolldown scalar. The cosmological inflation requires three monster groups having representation 196883 x 196883 x 196883 immediately after the Planck epoch from the supercooling transition to reheat where one copy degenerates to 196883^2/3. All of this involves product spaces of K3 x K3 where 4 dimensional volume expands introducing cosmological constant. This leaves two copies, 196883 x 196883 (two tensored N = 4 Super Yang Mills) to generate the standard model microphysics (includes SUGRA) at the end of the cosmological scalar rolldown at the end of the Electroweak epoch at 2.5 x 10^-9 s. All of this comes from 25 spatial dimensions wrapped on a circle (M^25 x S^1) of Planck radius at time t = 0.
