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, P
, Antiprisms, A, and Pyramids, Y, where 
specifies the number of sides of the polyhedron's base.
Operations to be performed on the polyhedron are then specified with lower-case letters preceding the capital letter.
