Comment(by hivert):
Hi Nicolas,
One quick remark. Since they are many different interesting code for
permutations. I'd rather call this file permutations codes and maybe make
an abstract class for those. For all the other code, the bijection is
different. If you are interested you can have a look at
Multivariate generalizations of the Foata-Schutzenberger
equidistribition (with F. Hivert and J.-C. Novelli), in Fourth
Colloquium on Mathematics and Computer Science: Algorithms, Trees,
Combinatorics and Probabilities, DMTCS Proceedings, 2006
