 These product polytopes are not strictly regular since they'll have more than one facet type, but some can represent lower symmetry of regular forms if all the orthogonal polytopes are identical.For example, the product "p"{}×"p"{} or of two 1-dimensional polytopes is the same as the regular "p"{4}2 or .More general products, like "p"{}×"q"{} have real representations as the 4-dimensional "p"-"q" duoprisms.
