disjoint permutations
Author: Marian Olejar, Jr. Created: Dec/08/2006 Last edit: Dec/08/2006
group theory:
Let a, b `in S_n` (symmetric group) are two permutations. The a and b are disjoint permutations if a(i) = i, then b(i) = i, and if b(j) = j, then a(j) = j. A family of permutations is disjoint if each pair of permutations is disjoint.
