The hecatonicosihecatonicosihexacosichoron, or hihix, is a nonconvex uniform polychoron that consists of 120 truncated great icosahedra, 600 truncated tetrahedra, and 120 small ditrigonal dodecicosidodecahedra. Three truncated great icosahedra, three truncated tetrahedra, and three small ditrigonal dodecicosidodecahedra join at each vertex.
It also has 120 great stellated dodecahedra and 600 tetrahedra as pseudofacets.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small dishexacosidishecatonicosachoron.
