Ray, thanks a lot for the link to that paper. I have downloaded it and will read it this weekend (I didn't say "understand" it, however!).

So Meng proved that there is only one solution, ignoring reflections of the original. The puzzle-maker claimed that there are more than one solution, but the puzzle-maker probably doesn't understand reflections.

thanks again
Don
