Prismatic uniform 4-polytope

[citation needed] These figures are analogous to the set of prisms and antiprism uniform polyhedra, but add a third category called duoprisms, constructed as a product of two regular polygons.

This family includes prisms for the 75 nonprismatic uniform polyhedra (of which 18 are convex; one of these, the cube-prism, is listed above as the tesseract).

[citation needed] The symmetry number of a polyhedral prism is twice that of the base polyhedron.

Their Coxeter diagram is of the form This family overlaps with the first: when one of the two "factor" polygons is a square, the product is equivalent to a hyperprism whose base is a three-dimensional prism.

The elements of a p,q-duoprism (p ≥ 3, q ≥ 3) are: There is no uniform analogue in four dimensions to the infinite family of three-dimensional antiprisms with the exception of the great duoantiprism.
