Duoprismatic swirltegum

A 'duoprismatic swirltegum'' is a member of a family of isotopic polychora obtained as duals to the duoprismatic swirlprisms. An m-n-gonal p-swirltegum generally has m*n*p identical cells. If m and n both equal 2, the result is a 2n-gonal duoprism, and if p = 2 the result is a m-n-gonal duoantitegum.

The cells of a duoprismatic swirltegum generally have 2 2p-gonal bases, 4 triangles, and 2p-2 tetragons for faces. If one of m and n equal 2, one pair of adjacent triangles collapses into another tetragonal face.
