Small ditrigonary hexacosicubitetrishecatonicosachoron

The small ditrigonary hexacosicubitetrishecatonicosachoron, or siddit xucthi, is a nonconvex uniform polychoron that consists of 600 cubes (some of which lie in the same hyperplane, forming 120 compound of five cubes), 120 great icosidodecahedra, 120 icosidodecahedra, 120 great ditrigonal dodecicosidodecahedra, 120 small icosicosidodecahedra, and 600 cubohemioctahedra. Four cubes (or two compounds), three great icosidodecahedra, three icosidodecahedra, six great ditrigonal dodecicosidodecahedra, six small icosicosidodecahedra, and six cubohemioctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
