A simple polyhedron, also called a simplicial polyhedron, is a polyhedron that is topologically equivalent to a sphere (i.e., if it were inflated, it would
produce a sphere) and whose faces are simple polygons.
The number of simple polyhedra on , 2, ... nodes are 0, 0, 1, 1, 1, 2, 5, 14, 50, 233, 1249,
... (OEIS A000109).
The skeletons of the simple polyhedra correspond to the triangulated
graphs, the smallest of which are illustrated above.
