General Notes on polyhedron Enumeration
333 444 55 7
A moderately large group of 48 members.
These poolyhedra either join a pentagon and the heptagon at a single vertex, or both pentagons join at a vertex.
polyhedra with 5-5-7 vertices, or pentagons separated by a single heptagon edge.
The remaining polyhedra have pentagons joined from opposite sides of the heptagon base.
