Great ditrigonary dishecatonicosihecatonicosachoron

The great ditrigonary dishecatonicosihecatonicosachoron, or gidtid hihy, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 rhombidodecadodecahedra, and 120 small ditrigonal dodecicosidodecahedra. Two great ditrigonary icosidodecahedra, six rhombidodecadodecahedra, and six small ditrigonal dodecicosidodecahedra join at each vertex.

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