Small ditrigonary prismatodishexacosidishecatonicosachoron

The small ditrigonary prismatodishexacosidishecatonicosachoron, or siddit padixady, is a nonconvex uniform polychoron that consists of 120 icosidodecahedra, 600 octahedra, 120 great icosicosidodecahedra, 720 decagonal prisms, and 600 cubohemioctahedra. Three icosidodecahedra, three octahedra, six great icosicosidodecahedra, 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.
