The small ditetrahedronary cubiprismatodishecatonicosachoron, or sidtacpady, is a nonconvex uniform polychoron that consists of 600 cubes (lying in the same hyperplanes, forming 120 compounds of five cubes), 120 dodecahedra, 1200 triangular prisms, and 120 small dodecicosidodecahedra. Eight cubes (or four compounds), four dodecahedra, twelve triangular prisms, and twelve small dodecicosidodecahedra join at each vertex.

Vertex coordinates

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