Hecatonicosihecatonicosintercepted hecatonicosachoron

The hecatonicosihecatonicosintercepted hecatonicosachoron, or hihiny, is a nonconvex uniform polychoron that consists of 120 small icosicosidodecahedra, 120 truncated dodecahedra, and 120 truncated great dodecahedra. Three small icosicosidodecahedra, three truncated dodecahedra, and three truncated great dodecahedra join at each vertex.

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

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