General Notes on polyhedron Enumeration

333345555

This class has 35 representatives. The unique quadrilateral face suggests using that face as a base might allow the best view. Unfortunately, interior faces are often tiny in this view. Each polyhedron is shown in all four pentagonal base views as well as the quadrilateral face view.

033, 022, 023, 024, 002, 003 and 027 (below) have three pentagon-quadrilateral edges and only one pair of triangles sharing edges.

020, 026, 019 (above) and 005, 018 and 017 (below) have only two pentagon-quadrilateral edges, meeting at a corner of the quadrilateral.

All the remaining polyhedra only two pentagon-quadrilateral edges on opposite sides of the quadrilateral.
