Small hecatonicosafaceted hecatonicosihexacosihecatonicosachoron

The small hecatonicosafaceted hecatonicosihexacosihecatonicosachoron, or shi fohixhi, is a nonconvex uniform polychoron that consists of 120 small ditrigonal dodecicosidodecahedra, 600 tetrahedra, and 120 truncated great dodecahedra. Three small ditrigonal dodecicosidodecahedra, one tetrahedron, and three truncated great dodecahedra join at each vertex.

It also has 600 tetrahedra and 120 truncated great dodecahedra as pseudofacets.

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