Small ditrigonary dishexacosicubitrishecatonicosachoron

The small ditrigonary dishexacosicubitrishecatonicosachoron, or sidtid xacthi, 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, 600 octahedra, 120 great ditrigonal dodecicosidodecahedra, 120 icosidodecadodecahedra, and 600 cubohemioctahedra. Four cubes (or two compounds), three great icosidodecahedra, three octahedra, six great ditrigonal dodecicosidodecahedra, six icosidodecadodecahedra, 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.
