Permutation graphs, fast forward permutations, and sampling the cycle structure of a permutation [PDF]
, 2003 A permutation P on {1,..,N} is a_fast_forward_permutation_ if for each m the computational complexity of evaluating P^m(x)$ is small independently of m and x. Naor and Reingold constructed fast forward pseudorandom cycluses and involutions.
