The grand ditetrahedronary retrodishecatonicosachoron, or gadtardy, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra and 120 great dodecicosidodecahedra. Four small ditrigonary icosidodecahedra and twelve great dodecicosidodecahedra join at each vertex.

Vertex coordinates[edit | edit source]

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