Grand retroditetrahedronary trishecatonicosachoron

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

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