A **tegmantitegmoid** is an isotopic polytope constructed as the dual to a prismantiprismoid. It is generally named for the duals of the polytopes that form the dual prismantiprismoid.

in 4D, an *m-n* tegmantitegmoid for even n) has 2*m*n cells, each of which is generally a 7-vertex hexahedron with mirror symmetry, obtained from truncating one of the base vertices of a kite pyramid, with 1 pentagon, 2 tetragons, and 3 triangles for faces. If m = 2, the pentagon at the bottom becomes a tetragon, and the resulting polyhedron is a mirror-symmetric distorted triangular prism with 2 triangles and 3 tetragons for faces.
