Duoexpandoprism

A duoexpandoprism is an isogonal polytope formed from the convex hull of two orthogonal duoprisms where one base is an expanded version of the other, forming two orthogonal rings of 2n n-gonal prisms. They are closely related to the duotruncatoprisms, differing only in the prisms and the number of rings. The simplest possible duoexpandoprism is the triangular duoexpandoprism, which is the convex hull of two orthogonal triangular-hexagonal duoprisms. The dual of a duoexpandoprism is a duoexpandotegum.

If one of the bases is a hypercube, then the resulting polytope will be the expanded hypercube, which can be made uniform. Other duoexpandoprisms are nonuniform.

Duoexpandoprisms can be blended with the base duoprisms to produce analogs of the four-dimensional inverted quasiprismatodishexadecachoron.
