Pentagonal icositetrahedral tegum

The pentagonal icositetrahedral tegum, also called the pentagonal icositetrahedral bipyramid, is a convex isochoric polychoron with 48 irregular pentagonal pyramids as cells. As the name usggests, it can be constructed as a tegum based on the pentagonal icositetrahedron.

In the variant obtained as the dual of the uniform snub cube, if the short edges of the pentagonal icositetrahedron have length 1, its height is approximately 10.48463.
