Great ditrigonary hecatonicosihecatonicosidishecatonicosachoron

The great ditrigonary hecatonicosihecatonicosidishecatonicosachoron, or gidthi hidy, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 rhombidodecadodecahedra, 120 small icosicosidodecahedra, and 120 great dodecicosahedra. Two great ditrigonary icosidodecahedra, six rhombidodecadodecahedra, six small icosicosidodecahedra, and six great dodecicosahedra join at each vertex.

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