Small tritrigonary hexacosicubitrishecatonicosachoron

The small tritrigonary hexacosicubitrishecatonicosachoron, or stut 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 icosahedra, 120 small dodecicosidodecahedra, and 120 great rhombicosidodecahedra. Two cubes (one compound), one tetrahedron, three truncated icosahedra, three small dodecicosidodecahedra, and six great rhombicosidodecahedra join at each vertex.

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