Haha, I spent about two hours fiddling about in the debugger and drawing bad diagrams to get an answer. I just checked and it turns out that I also got my personal best ranking on it too, though I'm not sure it should count :-)
True, I've just been looking at the comments on the other place, and pretty much everyone there seems to have resorted to figuring it out manually too.
If it had been more than 4 swaps, or larger distance swaps, this could have been a nightmare challenge.
