The dodecagonal tegum or twit, also called a dodecagonal dipyramib, is a tegum with a dodecagon as the midsection, constructed as the dual of a dodecagonal prism. It has 24 isosceles triangles as faces, with 2 order–12 and 12 order–4 vertices. .
In the variant obtained as the dual of a uniform dodecagonal prism, the side edges are times the length of the edges of the base dodecagon. Each face has apex angle and base angles . If the base dodecagon has edge length 1, its height is .
