Faceted pentachoric tetracomb

The faceted pentachoric tetracomb or fipte, also called the (pentagrammic-order) 600-cell honeycomb, is a compact regular star tiling of 4D hyperbolic space. 5 hexacosichora meet at each face in a pentagrammic arrangement, and 120 meet at each vertex.

It shares its vertices, edges, faces, and cells with the convex pentachoric tetracomb.
