Summary

Description

A great icosahedron with its pentagrammatic pyramids cut of

This figure is like an excavated dodecahedron with its self-intersecting hexagons replaced by convex hexagons.

It has the 30 edges of the dodecahedron and the 60 edges of the compound of five cubes.
Each of these pentagram edges belongs to only one hexagon. Arguably that makes is not a polyhedron.

This representation has pyritohedral symmetry, so the colors of some elements are those seen in the cube.
