Disphenoidal hecatonicosachoric tegum

The disphenoidal hecatonicosachoric tegum, also called the disphenoidal hecatonicosachoric bipyramid, is a convex isoteric polyteron with 240 identical phyllic disphenoidal pyramids as tera. As the name suggests, it can be constructed as a tegum based on the disphenoidal hecatonicosachoron.
