Discuss.
The first figure is correct, however the second is horribly wrong.
What you have done is doubled the number of possible openers for a single player, and then doubled it to count the number of possible openers for both players. You need to square the value.
With grip:
Number of possible openers for 1 player= 4^21
Number of possible openers for 2 players=4^42
Number of possible openers for 3 players=4^63
Number of possible openers for 4 players=4^84
Without grip:
Number of possible openers for 1 player= 4^20
Number of possible openers for 2 players=4^40
Number of possible openers for 3 players=4^60
Number of possible openers for 4 players=4^80
Some of you probably need this explaining, because form your posts, i gather that your method of thinking is slightly incorrect.
If you take the first joint as being the only joint, there are four possibilities of state. Meaning that you have four possible openers. Thus we get 4^1
If you take the first and second joints as being the only joints, you have four possibilities for the first, for each of these posibilities, the second provides another four possibilities. This we get 4^2
Add a third joint into the mix and we have another four possibilities ontop of what we already have, giving us 4^3 possible openers.
With uke having 20 joints, this logic gives us the figure of 4^20 joint arrangements for from the start of the game for a single player.
Taking grip into account, we can realise that there are two possibilities of grip state for each hand, meaning that there are now (2x2) extra player arangements to go with each exsistent arrangement, giving us the figure of 4^21 possible openers.
If you now include another player, for every possible opener the first player can have (which is 4^21), the second player can also have as many openers. This means that the number of openers for one player is squared when calculating the number of starters between two players:
4^21 squared is 4^42
If you want to get really picky, you could say that this value is wrong, because it counts uke doing move a, and tori doing move b as a different combination as uke doing move b and tori doing move a, when infact the two combinations owuld be exactly the same, apart form the payer doing the move is swapped round.
