Triangular-antitegmatic hexacontatetrachoric tegum

The triangular-antitegmatic hexacontatetrachoric tegum, also called the triangular-antitegmatic hexacontatetrachoric bipyramid, is a convex isoteric polyteron with 128 identical triangular antitegmatic pyramids as tera. As the name suggests, it can be constructed as a tegum based on the triangular-antitegmatic hexacontatetrachoron.
