Triangular-antitegmatic icosachoric tegum

The triangular-antitegmatic icosachoric tegum, also called the triangular-antitegmatic icosachoric bipyramid, is a convex isoteric polyteron with 40 identical triangular antitegmatic pyramids as tera. As the name suggests, it can be constructed as a tegum based on the triangular-antitegmatic icosachoron.
