I have been intrigued with Richter’s arXiv 0704.3091<\/a> “Triacontagonal Coordinates for the E8 root system” paper.<\/p>\n

Comparing nearest edges between Split Real Even (SRE) E8 and Richter’s Complex 4D Golden Ratio Petrie Projection Model:<\/p>\n

Please note, the vertex numbers are reordered from Richter’s paper in order to be consistent with ArXiv quant-ph 1502.04350<\/a> “Parity Proofs of Kochen-Specker theorem based on the Lie Algebra E8” by Aravind and Waegell. This paper uses the beautiful symmetries of E8 as a basis for proof sets related to the Bell inequalities of quantum mechanics. Below is a graphic showing that vertex number ordering:
\n\"\"<\/a><\/p>\n

Richter’s model with 74 nearest edges per vertex (Complex 4D Norm’d length Sqrt[2], with 8880 total):<\/p>\n

\"\"<\/a><\/p>\n

Richter’s model with only 26 nearest edges per vertex (Complex 4D Norm’d length 1, 3120 total):<\/p>\n

\"\"<\/a><\/p>\n

The above unity length edge pattern has is more consistent with the SRE E8 below. <\/p>\n

The SRE E8 Petrie Projection (with 56 Norm’d edge length Sqrt[2] for each vertex, 6720 total). This is equivalent to folding E8 to H4 with an 8×8 rotation matrix which creates a 4D-left H4+H4*Phi and a 4D-right H4+H4*Phi. <\/p>\n

Please note, the vertex number is that of the E8 vertices rotated (or “folded”) to H4 in 2D Petrie projection. The vertex numbers are in canonical binary order from E8’s 1:1 correspondence with the 9th row of the Pascal Triangle (eliminating the 16 generator\/anti-generator vertices of E8 found in the 2nd and 8th column of the Pascal Triangle). The graphic below shows the vertex number ordering:
\n\"\"<\/a><\/p>\n

Here we take the 4D-left half and project to two concentric rings of H4 and H4 Phi (Golden Ratio) with 56 nearest edges per vertex (Norm’d length of unity or Phi for each vertex):
\n\"\"<\/a><\/p>\n

The animation frames are sorted by the ArcTan[y\/x] of the vertex position in each ring (sorted H4*Phi outer to inner, then H4 outer to inner).<\/p>\n

BTW – if you find this information useful, or provide any portion of it to others, PLEASE make sure you cite this post. If you feel a blog post citation would not be an acceptable form for academic research papers, I would be glad to clean it up and put it into LaTex format in order to provide it to arXiv (with your academic sponsorship) or Vixra.
