Small tritrigonary prismatocubihecatonicosachoron

The small tritrigonary prismatocubihecatonicosachoron, or stutapchi, 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 small rhombidodecahedra, and 720 decagonal prisms. Two cubes (or one compound), three small rhombidodecahedra, and six decagonal prisms join at each vertex.

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