Retroinverted ditetrahedronary prismatodishecatonicosachoron

The retroinverted ditetrahedronary prismatodishecatonicosachoron, or ridatippady, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 720 pentagonal prisms, and 120 rhombidodecadodecahedra. Four small ditrigonary icosidodecahedra, twelve pentagonal prisms, and twelve rhombidodecadodecahedra join at each vertex.

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