Abstract |
|
In this paper the following result is obtained: Let α and β be two permutations such that αβ is transitive and αp = βq = 1 (where p and q are distinct primes). Then the set of all permutations commuting both with α and β is either reduced to the identity or one of the three cyclic groups Cp, Cq or Cpq. |
