Small ditrigonary hecatonicosiprismatohecatonicosihexacosichoron

The small ditrigonary hecatonicosiprismatohecatonicosihexacosichoron, or sidthiphix, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 great icosicosidodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Two great ditrigonary icosidodecahedra, six great icosicosidodecahedra, 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.
