Double gyroantitegmoid

A double gyroantitegmoid is an isotopic polytope formed as the dual to a double gyroantiprismoid.

In 4 dimensions, an n-gonal double gyroantitegmoid has 4n2 cells. If n > 2, each cell is a digonal-symmetric polyhedron with 11 faces and 16 vertices, with 8 kites, 2 irregular pentagons, and a mirror-symmetric octagon (which may turn into a tetrambus)) locally) as its faces. The [[digonal double gyroantitegmoid also exists but has a different cell shape, and in fact turns into an octagonal duoprism or an isotopic variant of it.
