Retroinverted ditetrahedronary hecatonicosiprismatohecatonicosachoron

The retroinverted ditetrahedronary hecatonicosiprismatohecatonicosachoron, or ridathiphi, is a nonconvex uniform polychoron that consists of 120 great stellated dodecahedra, 720 pentagrammic prisms, and 120 rhombicosahedra. Four great stellated dodecahedra, twelve pentagrammic prisms, and twelve rhombicosahedra join at each vertex.

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