Comments

Two faces are connected if they share an edge.

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

The icosidodecahedron is the polyhedral dual of the rhombic triacontahedron.

Examples

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