Great skewverted prismatohecatonicosidishexacosichoron

The great skewverted prismatohecatonicosidishexacosichoron, or gik vaphiddix, is a nonconvex uniform polychoron that consists of 600 cubohemioctahedra, 120 small dodecicosahedra, 720 decagonal prisms, and 600 truncated octahedra. One cubohemioctahedron, one small dodecicosahedron, two decagonal prisms, and two truncated octahedra join at each vertex.
