Duoexpandotegum

A duoexpandotegum is an isotopic polytope constructed as the dual of a duoexpandoprism. The simplest duoexpandotegum is the triangular duoexpandotegum.

in 4D, an n-gonal duoexpandotegum has 4n2 cells. Each cell is a bilaterally symmetric variant of the triangular antitegum with 2 kites and 4 irregular tetragons as faces.
