well, that was kinda what I was scared of.
See, I hoped you were just trying to work out the 'potential'. If you are trying to work out according to moves etc. then give up! It's too hard. Plus I don't know if what you are trying to do is valid... I mean, what limits are you setting?
If you are talking about an open-ended game, then my answer is correct as the potential number. However I think the question is a bit odd in the first place.
Why are you trying to do this? What restrictions are you imposing? The way you are headed is into fiendishly complex maths
