Hexacosihecatonicosidishecatonicosachoron

The hexacosihecatonicosidishecatonicosachoron, or xhidy, is a nonconvex uniform polychoron that consists of 600 octahemioctahedra, 120 truncated dodecahedra, 120 quasitruncated great stellated dodecahedra, and 120 icosidodecatruncated icosidodecahedra. 1 truncated dodecahedron, 1 quasitruncated great stellated dodecahedron, 1 octahemioctahedron, and 2 icosidodecatruncated icosidodecahedra join at each vertex.

It is in the same regiment as the hecatonicosihexacosidishecatonicosachoron.
