Small ditrigonary prismatohecatonicosihexacositrishecatonicosachoron

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