Small ditrigonary prismatohecatonicosihexacosidishecatonicosachoron

The small ditrigonary prismatohecatonicosihexacosidishecatonicosachoron, or siddit phixady, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 icosidodecadodecahedra, 120 great ditrigonal dodecicosidodecahedra, 720 decagonal prisms, and 600 cubohemioctahedra. Two small ditrigonary icosidodecahedra, six icosidodecadodecahedra, six great ditrigonal dodecicosidodecahedra, twelve decagonal 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.
