Abstract

In this paper we present a systematic technique for obtaining all the input sequences that are mapped by a given permutation either to themselves or to shifted versions of themselves (generically called permutation fixed points). Subsequently, we present a new class of permutations that nearly achieve the lowerbound on the number of possible fixed points associated with a given permutation of prime length p.
