Abstract

A permutation on n elements is called a k-derangement (kn) if no k-element subset is mapped to itself. One can form the k-derangement graph on the set of all permutations on n elements by connecting two permutations σ and τ if στ1 is a k-derangement. We characterize when such a graph is connected or Eulerian. For  n an odd prime power, we determine the independence, clique and chromatic numbers of the 2-derangement graph.
