= Conway polyhedron notation
{wiki=Conway_polyhedron_notation}
Conway polyhedron notation (CPN) is a system devised by mathematician and crystallographer Sir Roger Penrose to succinctly describe the three-dimensional shapes (polyhedra) that can be formed by truncating the vertices of a polyhedron. It utilizes a series of letters and symbols to represent the faces, edges, and vertices of these geometric figures, serving as a shorthand that can capture the essential structure of a polyhedron in a compact form.
