Radial ditrigonary trishecatonicosachoron

The radial ditrigonary trishecatonicosachoron, or ridtithi, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 great icosicosidodecahedra, and 120 small icosicosidodecahedra. Two ditrigonary dodecadodecahedra, six great icosicosidodecahedra, and six small icosicosidodecahedra join at each vertex.

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