The triakis icosahedral tegum, also known as the triakis icosahedral bipyramid, is a convex isochoric polychoron with 120 sphenoids as cells. As the name suggests, it can be constructed as a tegum based on the triakis icosahedron.
In the variant obtained as the dual of the uniform truncated dodecahedral prism, if the short edges of the triakis icosahedron have length 1, its height is .
