The small tritrigonary hexacosidishecatonicosihexacosichoron, or stut xidhix, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 600 octahemioctahedra, 120 truncated dodecahedra, and 120 small dodecicosahedra. One tetrahedron, three octahemioctahedra, three truncated dodecahedra, and three small dodecicosahedra join at each vertex.

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