Always nice when the minimums work out perfectly!

It was intended as a fun bonus for people who would spot it - since the minimal p-ring adds to 42! But it was not needed for the solve.
And now it no longer has 42 solves :)

I sincerely hope this puzzle doesn't get any more solves...ever ;)

Thanks for your kind comments - I promise the 42 is in there, but you don't need to use it to finish the puzzle :)

I found this quite challenging, maybe I missed a few easy tricks? Thanks for a nice puzzle.
