Small prismatotrishecatonicosachoron

The small prismatotrishecatonicosachoron, or sipthi, is a nonconvex uniform polychoron that consists of 1200 triangular prisms, 120 truncated great dodecahedra, 120 great dodecicosidodecahedra, and 120 quasitruncated dodecadodecahedra. 1 triangular prism, 1 truncated great dodecahedron, 1 great dodecicosidodecahedron, and 2 quasitruncated dodecadodecahedra join at each vertex.
