Every move I have that swaps edges does TWO pairs are a > time, so I can't get there with what I have. Or can I? I'm not familiar with Square-1...but if, as seems lkely, it's a square that you have to get into some arrangement, then consider turning the whole puzzle 90 or 180 degrees and trying again; that may introduce an odd permutation and thus make a solution possible. Or depending on the definition of "solved" - as I say, I don't know the puzzle - maybe go for a mirror-reflected state. der Mouse mouse@collatz.mcrcim.mcgill.edu
