Small tritrigonary disprismatohexacosicubihecatonicosachoron

The small tritrigonary disprismatohexacosicubihecatonicosachoron, or stut dapexchi, 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 pentagrammic prisms, 120 small icosicosidodecahedra, and 1200 hexagonal prisms. Two cubes (one compound), one tetrahedron, three pentagrammic prisms, three small icosicosidodecahedra, and six hexagonal prisms join at each vertex.

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