Small tritrigonary dishexacosidishecatonicosachoron

The small tritrigonary dishexacosidishecatonicosachoron, or stut dixady, is a nonconvex uniform polychoron that consists of 600 regular tetrahedra, 120 truncated icosahedra, 600 octahemioctahedra, and 120 great ditrigonary icosidodecahedra. 1 tetrahedron, 3 truncated icosahedra, 3 octahemioctahedra, and 1 great ditrigonary icosidodecahedron join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small tritrigonary prismatohecatonicosidishexacosichoron.
