Grand ditrigonary hecatonicosihexacosidishecatonicosachoron

The grand ditrigonary hecatonicosihexacosidishecatonicosachoron, or gadthixady, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 rhombidodecadodecahedra, 120 small icosicosidodecahedra, and 600 octahemioctahedra. Two great ditrigonary icosidodecahedra, six rhombidodecadodecahedra, six small icosicosidodecahedra, and six octahemioctahedra join at each vertex.
