Great ditrigonary trishecatonicosihecatonicosachoron

The great ditrigonary trishecatonicosihecatonicosachoron, or giddit thihi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 great icosidodecahedra, 120 icosidodecahedra, and 120 small ditrigonal dodecicosidodecahedra. Two great ditrigonary icosidodecahedra, three great icosidodecahedra, three icosidodecahedra, 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.
