Great tritrigonary hexacosicubitrishecatonicosachoron

The great tritrigonary hexacosicubitrishecatonicosachoron, or getit xacthi, is a nonconvex uniform polychoron that consists of 600 cubes (some of which lie in the same hyperplanes, forming 120 compound of five cubes), 600 tetrahedra, 120 truncated great icosahedra, 120 great dodecicosidodecahedra, and 120 great quasitruncated icosidodecahedra. Two cubes (one compound), one tetrahedron, three truncated great icosahedra, three great dodecicosidodecahedra, and six great quasitruncated icosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great tritrigonary hexacositrishecatonicosachoron.
