In Response To: How to nactate 52S-54-g 13/9 8/3* (Nack Ballard)

It seems to me that for any play, a Nactation character can be determined by a set of rules and on those grounds is programmable

O.K., so let me check something.

1. What is the maximum possible number of different legal plays in a backgammon position? I seem to recall that there are positions where there are hundreds of ways to play 11. Call this number N.

2. Are there at least N different Nactation characters? If so, have enough rules for Nactation been published for someone to program a computer to assign the correct character to each of the N plays?
