Ditrigonary hecatonicosidishecatonicosachoron

The ditrigonary hecatonicosidishecatonicosachoron, or dithidy, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 great ditrigonal dodecicosidodecahedra, and 120 small ditrigonal dodecicosidodecahedra. Two ditrigonary dodecadodecahedra, 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.
