520 3 |a We find limit distributions of the maximum size of a tree and of the number of trees of given size in an unlabelled random forest consisting of N rooted trees and n non-root vertices provided that N, n → ∞ so that 0 < C 1 ≤ N / √n ≤ C 2 < ∞. With the use of these results, for the unlabelled graph of a random single-valued mapping of the set {1, 2, . . .,n} into itself we prove theorems on the limit behaviour of the maximum tree size and of the number of trees of size r as n → ∞ in the cases of fixed r and r/n 1/3 ≥ C 3 > 0.
