Grand retroditetrahedronary dishecatonicosachoron

The grand retroditetrahedronary dishecatonicosachoron, or gardatady, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra and 120 small ditrigonary icosidodecahedra. Six great icosidodecahedra and four small ditrigonary icosidodecahedra join at each vertex.

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