  2. Good luck with this one. Be sure to beat the 2x2 and 3x3 ones before attempting this monster. This one is for Mike Daas who wanted to see a seriously difficult puzzle from graph theory.

    Sokoban Online supports even larger shifting lock puzzles, but I believe that if you can beat this one you can beat them all with sufficient patience.

    I'm not even going to try to pretend I solved this one by hand.

      @qqwref: I'm impressed you solved all of them so fast yesterday! I am also curious; what did you use as an assist tool? Something you designed or a package online?

      @mathmasterzach: I used a program called ksolve+ which can solve permutation puzzles as well as Rubik's Cube-type puzzles. This one is generated by two 16-cycles. After I generated some solutions, I then checked which of them would have the least block pushes (since each move can only be done in one direction).
