Great hexacosifaceted hexacosidishecatonicosachoron

The great hexacosifaceted hexacosidishecatonicosachoron, or gix fixady, is a nonconvex uniform polychoron that consists of 120 great icosicosidodecahedra, 120 dodecahedra, and 600 truncated tetrahedra. Three great icosicosidodecahedra, one dodecahedron, and three truncated tetrahedra join at each vertex.

It also has 120 truncated icosahedra and 600 tetrahedra as pseudofacets.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great ditrigonal hecatonicosihexacosihecatonicosachoron.
