Conway Polyhedron Notation
A notation for polyhedra which begins by specifying a "seed" polyhedron using a capital letter. The Platonic solids are denoted T (tetrahedron), O (octahedron), C (cube), I (icosahedron), and D (dodecahedron), according to their first letter. Other polyhedra include the prisms, Pn, antiprisms, An, and pyramids, Yn, where n>=3 specifies the number of sides of the polyhedron's base.
Operations to be performed on the polyhedron are then specified with lowercase letters preceding the capital letter.
