Small hexacosihecatonicosidishecatonicosachoron

The small hexacosihecatonicosidishecatonicosachoron, or sixhidy, is a nonconvex uniform polychoron that consists of 600 regular tetrahedra, 120 great stellated dodecahedra, 120 truncated dodecahedra, and 120 truncated great dodecahedra. 1 tetrahedron, 1 great stellated dodecahedron, 3 truncated dodecahedra, and 3 truncated great dodecahedra join at each vertex.

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