Further equidistribution of set-valued statistics on permutations
Jianxi Mao, Jiang Zeng · arXiv (Cornell University) · 2019
We construct bijections to show that two pairs of sextuple set-valued statistics of permutations are equidistributed on symmetric groups. This extends a recent result of Sokal and the second author valid for integer-valued statistics as well as a previous result of Foata and Han for bivariable set-valued statistics.
