The small tesseractifaceted cubitesseractihexadecachoron, or stefacoth, is a nonconvex uniform polychoron that consists of 16 tetrahedra, 24 cubes, and 8 small rhombicuboctahedra. One tetrahedron, three cubes, and three small rhombicuboctahedra join at each vertex.

It also has 8 cubes and 32 triangular prisms as pseudofacets.
