Retroinverted ditetrahedronary trishecatonicosachoron

The retroinverted ditetrahedronary trishecatonicosachoron, or ridatathi, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 dodecahedra, and 120 dodecadodecahedra. Four small ditrigonary icosidodecahedra, four dodecahedra, and six dodecadodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the ditetrahedronary dishecatonicosachoron.
