i think there are many numbers for independants, not just 23. that's my only guess.

the idiot/easy but tedious method:

set 31 to be allies with every number 1-100. if there are some nations you know the # for and dont want to be allied, omit them.

i would think this would do it. i have never done this, so, thats my best help
