报告摘要：A regular polyhedron of type {p, q} has at least 2pq flags, and it is calledtight if it has exactly 2pq flags. The values of p and q for which there exist tight orientably regular polyhedra were previously known.We determine for which values ofp and q there is a tight non-orientably regular polyhedron of type {p, q}. Furthermore,we completely classify tight regular polyhedra in terms of their automorphism groups.
