Great ditrigonary hecatonicosihecatonicosihexacosidishecatonicosachoron

The great ditrigonary hecatonicosihecatonicosihexacosidishecatonicosachoron, or gidthihixady, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 small icosicosidodecahedra, 120 rhombidodecadodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Two great ditrigonary icosidodecahedra, six small icosicosidodecahedra, six rhombidodecadodecahedra, twelve quasitruncated dodecadodecahedra, and six cubohemioctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
