This non-convex polyhedron illustrates three related equations: 60 = (12)(5) — twelve sets of five yellow hexagons, 60 = (30)(2) — thirty pairs of red isosceles triangles, and 60 = (20)(3) — twenty sets of three yellow hexagons.
For a second look at this polyhedron, I made the triangles invisible, and then put the rest of the model in “rainbow color mode.”
I made both of these images using Stella 4d, which you can try for free at this website.
Stunning! and Stunning!
