Hecatonicosihexacosidishecatonicosachoron

The hecatonicosihexacosidishecatonicosachoron, or hixady, is a nonconvex uniform polychoron that consists of 600 cuboctahedra, 120 truncated dodecahedra, 120 quasitruncated great stellated dodecahedra, and 120 quasitruncated dodecadodecahedra. 1 truncated dodecahedron, 1 quasitruncated great stellated dodecahedron, 1 cuboctahedron, and 2 quasitruncated dodecadodecahedra join at each vertex.
