I agree with Garrett Lisi. It’s sets and geometry.

The Lie E8 is a beautiful structure mathematically with 248 dimensions:
However, I think what he wants to achieve is even simpler to model physically.
This is a 3V Icosahedron Geodesate:
This structure gives us 92 vertexes (entities) and 270 edges (associations) or 362 particles.
Employing Occam’s Razor, I suggest that some form of Icosahedron Geodesate theory is more likely the answer.
