Ho-Mg-Zn QuasiCrystal Electron Diffraction with E8 5Cube Projection

This is an image of the electron diffraction pattern of an icosahedral Zn-Mg-Ho quasicrystal with an overlay of a 5-Cube projection from the 240 vertices of the split real even E8 Lie Group.
The basis vectors for the E8 projection are shown (1:1 with the ring of gray vertices with the last 3 of 8 dimensions 0).
There are 2480 overlapping edge lines from the 240 E8 vertices. They have norm’d unit length calculated from the 5 non-zero projected dimensions of E8. Of these, 32 inner vertices and 80 edges belong to the 5D 5-Cube (Penteract) proper. Edges are shown with colors assigned based on origin vertex distance from the outer perimeter.
The vertex colors of the 5-Cube projection represent E8 vertex overlaps. These are:
InView vertices={color{overlap,count},…}Total
{LightGreen{1,20},Pink{5,20},Gray{10,10},Orange{20,1}}51
All vertices={color{overlap,count},…}Total
{LightGreen{1,20},Pink{5,100},Gray{10,100},Orange{20,20}}240
A related projection of a 6D 6-Cube (Hexeract) into a perspective 3D object using the Golden Ratio [Phi]. This particular projection is used to understand the structure of QuasiCrystals. The specific basis vectors are:
x = {1, [Phi], 0, -1, [Phi], 0}
y = {[Phi], 0, 1, [Phi], 0, -1}
z = {0, 1, [Phi], 0, -1, [Phi]}
There are 64 vertices and 192 unit length edges forming pentagonal symmetry along specific axis (as well as hexagonal symmetries on other axis).

More SciAm images
An emulation (w/particle labels) of an E8 embedding from Lisi’s Dec. 2010 Scientific American article. There are 2 rings of 12 groups of 8 fermions (with 2 overlapping in the center) and 4 rings of 12 bosons.
A few new projections in honor of Garrett’s second SciAm Article this year.
Another article in SciAm
I created an emulation of the article pic (bottom)
and added a well known Lisi projection (middle),
and one of my own clearly showing 2 rings of 12 groups of 8 Fermions and 4 Boson rings of 12 :
