Description
In this paper we study the k-fixed-points statistic over the symmetric group. We will give some combinatorial interpretations to the relations defining them as well as their generating functions. A combinatorial interpretation directly on derangements of the famous relation on derangement numbers dn = ndn−1 + (−1)n will be given
