Rhombic hexacosidishecatonicosachoron

The rhombic hexacosidishecatonicosachoron, or rixady, is a nonconvex uniform polychoron that consists of 600 cubohemioctahedra, 120 quasitruncated dodecadodecahedra, and 120 icosidodecatruncated icosidodecahedra. One cubohemioctahedron, two quasitruncated dodecadodecahedra, and two icosidodecatruncated icosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the hecatonicosihexacosidishecatonicosachoron.
