Small ditrigonary trishecatonicosiprismatohexacosichoron

The small ditrigonary trishecatonicosiprismatohexacosichoron, or siddit thipix, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 120 icosidodecahedra, 120 icosidodecadodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Three great icosidodecahedra, three icosidodecahedra, six icosidodecadodecahedra, twelve decagrammic prisms, 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.
