An efficient construction of a permutation network has been proposed by Waksman. However, his construction is only for permutation networks with 2k inputs. This paper provides a construction of permutation networks with arbitrary number of inputs that is an extension of Waksman's construction. By applying our construction to Abe's Mix-net, we can improve the efficiency of the Mix-net.
