High Quality Content by WIKIPEDIA articles! In mathematics, a regular polytope is a polytope whose symmetry is transitive on its flags, thus giving it the highest degree of symmetry. All its elements or j-faces (for all 0 ? j ? n, where n is the dimension of the polytope) ? cells, faces and so on ? are also transitive on the symmetries of the polytope, and are regular polytopes of dimension ? n. Regular polytopes are the generalized analog in any number of dimensions of regular polygons (for example, the square or the regular pentagon) and regular polyhedra (for example, the cube). The strong symmetry of the regular polytopes gives them an aesthetic quality that interests both non-mathematicians and mathematicians.
