That's for d%; I was referring to "Cyborg Commando" which had a d10x, which is (d10)*(d10), making a 1,3 combination 3 always. You'd never get a prime number larger than 7 under the d10x system. combo = Hash.new(0) 1.upto(10) { |i| 1.upto(10) { |j| combo[i * j] += 1 } } There are 42 possible values here, and 9 values (6, 8, 10, 12, 18, 20, 24, 30, 40) appear four times each. Four values (4, 9, 16, 36) appear three times each, 23 values twice each, and 6 values once. It was a truly fucked up system. I think it's because he was mad to be ousted. -austin -- Austin Ziegler * halostatue / gmail.com * Alternate: austin / halostatue.ca
