* The case n=2 equally would be considerable here by concept, it just has a different incidence matrix as the n-gons become degenerate. Further their tets would become corealmic and thus combine to trits. – Conversely, the other extreme at n=4 makes the n-cupolas corealmic, so that the two remaining squacues combine there into a single squobcu. – Outside that intervall these polychora won't be CRFs any longer.
