General Notes on polyhedron Enumeration

---

A fairly large group with 43 members. Since there's a unique heptagon face, only one view is needed.

333344567

There are no cases where the pentagon is separated from the heptagon, no cases where the pentagon is joined to the heptagon at just one vertex, and no cases with a 5-6-7 vertex. Both would require too many vertices.
