Duoantiprism

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