Great hexacosiprismatodishecatonicosachoron

The great hexacosiprismatodishecatonicosachoron, or gixipady, is a nonconvex uniform polychoron that consists of 720 pentagonal prisms, 600 truncated tetrahedra, 120 great ditrigonal dodecicosidodecahedra, and 120 great quasitruncated icosidodecahedra. 1 pentagonal prism, 1 truncated tetrahedron, 1 great ditrigonal dodecicosidodecahedron, and 2 great quasitruncated icosidodecahedra join at each vertex.
