Duoantiprism

A duoantiprism is an isogonal polytope formed from the alternation of a duoprism formed as the Cartesian product of two polytopes, if and and only if both base polytopes are alternable, and are generally nonunfiorm. The simplest non-trivial duoantiprism is the hexadecachoron (considered as a 2-2 duoantiprism), while the only uniform duoantiprisms are the hexadecachoron (and any demihypercube) and the great duoantiprism (5-5/3 duoantiprism). The dual of a duoantiprism is a duoantitegum.
