Great tritrigonary disprismatohecatonicosicubihexacosichoron

The great tritrigonary disprismatohecatonicosicubihexacosichoron, or getit diphicax, 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, 720 pentagonal prisms, 120 great ditrigonal dodecicosidodecahedra, and 720 decagrammic prisms. Two cubes (one compound), one tetrahedron, three pentagonal prisms, three great ditrigonal dodecicosidodecahedra, 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.
