The octagonal tegum or ot, also called an octagonal bipyramid, is a tegum with an octagon as the midsection, constructed as the dual of an octagonal prism. It has 16 isosceles triangles as faces, with 2 order–8 and 8 order–4 vertices.
In the variant obtained as the dual of a uniform octagonal prism, the side edges are times the length of the edges of the base octagon. Each face has apex angle and base angles . If the base octagon has edge length 1, its height is .
