Great retroditetrahedronary trishecatonicosachoron

The great retroditetrahedronary trishecatonicosachoron, or grad tathi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 great stellated dodecahedra, and 120 icosidodecadodecahedra. Four great ditrigonary icosidodecahedra, four great stellated dodecahedra, and twelve icosidodecadodecahedra join at each vertex.

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