i thank you both for noticing this -- my pattern is just the way i happened to invent it, and i know-not how to find all the equivalent patterns

it would indeed be nice to use the one with the greatest symmetry

pm submissions to g.r.emlin will now reject puzzles that have a permutation with a higher dihedral symmetry order
you can use -f%#sc in my solver to symmetrize any puzzle [ edit to the highest possible dihedral symmetry order ] (its not fast)
it prints asymmetric if there is no permutation with non-trivial dihedral symmetry
it produces this variant

a couple of times already i've tried to promote a status-format of one-per-line

much more readable to a human
