Schläfli symbol




A notation, devised by Ludwig Schläfli, which describes the number of edges of each polygon meeting at a vertex of a regular or semi-regular tiling or solid. For a Platonic solid, it is written {p, q}, where p is the number of sides each face has, and q is the number of faces that touch at each vertex.
