The self-routing technique using control tags on multiple-pass perfect-shuffle networks is generalized. In particular, they show that bit-permute-complement permutations can be realized and unscrambled in (2n-1) passes or less, where n=log/sub 2/N, N being the number of terminals on either side. They also show that most of the frequently used permutations are in the intersection of omega-realiz
