Great tritrigonary trishecatonicosiprismatocubihexacosichoron

The great tritrigonary trishecatonicosiprismatocubihexacosichoron, or getit thipcax, is a nonconvex uniform polychoron that consists of 600 cubes (some of which lie in the same hyperplanes, forming 120 compound of five cubes), 120 truncated great icosahedra, 120 quasitruncated great stellated dodecahedra, 600 octahemioctahedra, 120 quasirhombicosidodecahedra, and 720 decagrammic prisms. Two cubes (one compound), three truncated great icosahedra, three quasitruncated great stellated dodecahedra, three octahemioctahedra, three quasirhombicosidodecahedra, and six decagrammic prisms join at each vertex.

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