Comments

Two faces are connected if they share an edge.

These are "free" polyforms because both rotations and reflections are allowed.

The truncated dodecahedron is the polyhedral dual of the triakis icosahedron.

Examples

			a(1) = 2 because the truncated dodecahedron is not face transitive, but has two distinct orbits of faces: (1) triangles and (2) decagons.
