 While 1-polytopes can have unlimited "p", finite regular complex polygons, excluding the double prism polygons "p"{4}2, are limited to 5-edge (pentagonal edges) elements, and infinite regular apeirogons also include 6-edge (hexagonal edges) elements.Shephard originally devised a modified form of Schläfli's notation for regular polytopes.For a polygon bounded by "p"1-edges, with a "p"2-set as vertex figure and overall symmetry group of order "g", we denote the polygon as "p"1("g")"p"2.
