Truncated decachoron

The truncated decachoron or tadeca is a convex isogonal polychoron that consists of 10 ditruncated tetrahedra and 30 tetragonal disphenoids formed by truncating the decachoron.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\sqrt3$$ ≈ 1:1.73205.
