We study the asymptotic behavior of the maximal multiplicity µ n = µ n (λ) of the parts in a partition λ of the positive integer n, assuming that λ is chosen uniformly at random from the set of all such partitions. We prove that πµ n /(6n) 1/2 converges weakly to max j X j /j as n → ∞, where X 1 , X 2 , . . . are independent and exponentially distributed random variables with common mean equal to 1.
