Small ditetrahedronary cubidishecatonicosachoron

The small ditetrahedronary cubidishecatonicosachoron, or sidtacady, is a nonconvex uniform polychoron that consists of 600 cubes, 120 icosidodecahedra, and 120 small rhombicosidodecahedra. Eight cubes, six icosidodecahedra, and twelve small rhombicosidodecahedra join at each vertex.

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