Tri-icositetradiminished hexacosichoron

The tri-icositetradiminished hexacosichoron, tetragonal-antiwedge heptacontadichoron, tetragonal-antiwedge hexafold ditetraswirlchoron, or tridex, is a noble polychoron with 72 tetragonal antiwedges as cells. It can be obtained by diminishing the vertices of three icositetrachora from the hexacosichoron.

The ratio between the longest and shortest edges is 1:$$\frac{1+\sqrt5}{2}$$ ≈ 1:1.61803.
