Great hecatonicosidishecatonicosachoron

The great hecatonicosidishecatonicosachoron, or ghidy, is a nonconvex uniform polychoron that consists of 120 truncated great icosahedra, 120 small dodecicosahedra, and 120 truncated great dodecahedra. Two truncated great icosahedra, two small dodecicosahedra, and four truncated great dodecahedra join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small sphenoverted trishecatonicosachoron.
