Rectification wrt. a non-regular polytope is meant to be the singular instance of truncations on all vertices at such a depth that the hyperplane intersections on the former edges will coincide (provided such a choice exists). Within the specific case of tah as a pre-image these intersection points might differ on its 2 edge types. Therefore tah cannot be rectified (within this stronger sense). Nonetheless the Conway operator of ambification (chosing the former edge centers generally) clearly is applicable. This would result in 2 different edge sizes in the outcome polychoron. That one here is scaled such so that the smaller one becomes unity. Then the medium edge will have size q = sqrt(2) and the longer one has size h = sqrt(3).
All d = 3 edges, used in the below descriptions, only qualify as pseudo edges wrt. the full polychoron.
