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 n/d-p as a pre-image these intersection points might differ on its 2 edge types. Therefore n/d-p in generally 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 polyhedron. That one here is scaled such so that the square sides become unity. Then the shorter edge will have size c = x(n/d)/x(4) = sqrt(2) cos(π d/n).

All q = sqrt(2) edges, used in the below descriptions, only qualify as pseudo edges wrt. the full polyhedron.

Note that the below description also could be scaled by q into a further convenient form ouo-n/d-yoy&#qt = ou uo-n/d-oy&#zq, where for abbreviation y = x(n/d), but then the circumradius and given heights too had to be rescaled accordingly for sure. Thereby the u-edges then would qualify as those pseudo edges.
