The symmetric group of Degree is the Group of all Permutations on symbols. is therefore of Order and contains as Subgroups every Group of Order . The number of Conjugacy Classes of is given by the Partition Function P.
Netto's Conjecture states that the probability that two elements and of a symmetric group generate the entire group tends to 3/4 as . This was proven by Dixon in 1967.
