Prismatorhombated stellated hecatonicosachoron

The prismatorhombated stellated hecatonicosachoron, or pirshi, is a nonconvex uniform polychoron that consists of 720 pentagrammic prisms, 1200 hexagonal prisms, 120 truncated icosahedra, and 120 rhombidodecadodecahedra. 1 pentagrammic prism, 2 hexagonal prisms, 1 truncated icosahedron, and 1 rhombidodecadodecahedron join at each vertex. It can be obtained by runcitruncating the faceted hexacosichoron.
