Great hecatonicosiprismatodishecatonicosachoron

The great hecatonicosiprismatodishecatonicosachoron, or ghipady, is a nonconvex uniform polychoron that consists of 720 pentagonal prisms, 120 truncated dodecahedra, 120 great icosicosidodecahedra, and 120 great rhombicosidodecahedra. 1 pentagonal prism, 1 truncated dodecahedron 1 great icosicosidodecahedron, and 2 great rhombicosidodecahedra join at each vertex.
