Tetrakis hexahedral tegum

The tetrakis hexahedral tegum, also called the tetrakis hexahedral bipyramid, is a convex isochoric polychoron with 48 sphenoids as cells. As the name suggests, it is a tegum based on the tetrakis hexahedron.

In the variant obtained as the dual of the uniform truncated octahedral prism, if the tetrakis hexahedron's short edge has length 1, its height is $$4\sqrt2 ≈ 5.65685$$.
