Hi! I'm developing solution to this task using transpositions, therefore some results can be long until canonical form is reached. (note the following example is still correct permutation)

The animation went crazy when I tried this example: rice-cire 10,12,01,12,21,10,12,01,12,21,10,12,01,12,21,12

It's just a minor bug, I guess, still bug though.
