Description
The number of nontrivial cycles in the cycle decomposition of a permutation.
This statistic is equal to the difference of the number of cycles of $\pi$ (see St000031The number of cycles in the cycle decomposition of a permutation.) and the number of fixed points of $\pi$ (see St000022The number of fixed points of a permutation.).
This statistic is equal to the difference of the number of cycles of $\pi$ (see St000031The number of cycles in the cycle decomposition of a permutation.) and the number of fixed points of $\pi$ (see St000022The number of fixed points of a permutation.).
Map
Lehmer code rotation
Description
Sends a permutation $\pi$ to the unique permutation $\tau$ (of the same length) such that every entry in the Lehmer code of $\tau$ is cyclically one larger than the Lehmer code of $\pi$.
Map
first fundamental transformation
Description
Return the permutation whose cycles are the subsequences between successive left to right maxima.
Map
to 132-avoiding permutation
Description
Sends a Dyck path to a 132-avoiding permutation.
This bijection is defined in [1, Section 2].
