Ditrigonary hecatonicositrishecatonicosachoron

The ditrigonary hecatonicositrishecatonicosachoron, or dithithi, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 120 icosidodecahedra, 120 great ditrigonal dodecicosidodecahedra, and 120 small ditrigonal dodecicosidodecahedra. Three great icosidodecahedra, three icosidodecahedra, six great ditrigonal dodecicosidodecahedra, 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.
