An experimental generator for analysing distinct-entry 6×6, 8×8, 9×9 and 10×10 squares after mirroring, rotating upside down, or applying both transformations.
Created by Inder J. Taneja
0, 1, 8 stay the same in a mirror; 2 and 5 swap with each other. (3, 4, 6, 7, 9 have no real mirror image.)
Zero appears only in an interior digit position, so neither the original nor the transformed entry begins with zero.
