The rhombic triacontahedral tegum, also called the rhombic triacontahedral bipyramid, is a convex isochoric polychoron with 60 rhombic pyramids as cells. As the name suggests, it can be constructed as a tegum based on the rhombic triacontahedron.
In the variant obtained as the dual of the uniform icosidodecahedral prism, the height from the top to the bottom edges is times the edge length of the base rhombic triacontahedron.
