Query: An involution on derangements preserving excedances and right-to-left
  minima   We give a bijective proof of a result by R.~Mantaci and F.~Rakotondrajao from
2003, regarding even and odd derangement with a fixed number of excedances. We
refine this result by also considering the set of right-to-left minima.
