i reackon youv'e seen it already, the problem is to rearrange the next numbers in the fixed order:
1 2 3 4
5 6 7 8
9 11 10
when you have at the last entry a vacant place you need to put it in order.
this is from the text of edwin h. connell, and i think it's impossible (after a lot of trial & error on my behalf), now my question is how do you prove/disprove my assertion?
