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.
