Thanks and same to you.

Heck no!
Are you on Win 7?
I have not even scratched the surface because I am still wrestling with a representation of the puzzle itself. It is unlikely that I will get far even when I solve that small problem because I do not understand how the program should pick from its many choices.
Did you?
I will try one and see what comes up.
But programming it is what I am thinking.
Mathematica?
There is some math that tells you whether it is solveable or not but I have forgotten it.
Ok, so how to do it?
Some positions are not possible but others are.
The 15 puzzle is unsolvable.
