Great skewverted prismatohecatonicosidishecatonicosachoron

The great skewverted prismatohecatonicosidishecatonicosachoron, or gik viphidy, is a nonconvex uniform polychoron that consists of 120 great quasitruncated icosidodecahedra, 120 great rhombidodecahedra, 120 small dodecicosahedra, and 720 decagonal prisms. Two great quasitruncated icosidodecahedra, one great rhombidodecahedron, one small dodecicosahedron, and two decagonal prisms join at each vertex.
