Faceted hexacosichoron

The faceted hexacosichoron, or fix, also commonly called the icosahedral 120-cell, is one of the 10 regular star polychora]]. It has 120 icosahedra as cells, joining 5 to an edge and 12 to a vertex in the form of a great dodecahedron.

As the name suggests, it is a faceting of the hexacosichoron, sharing its vertices, edges, and faces. The icosahedral cells are the same as the vertex figures of the hexacosichoron.
