| Mar 8, 2020 at 21:41 | comment | added | user35313 | Not directly related but in the case of 312-avoiding permutation, the map in Section 3 of the Bandlow-Killpatrick paper might be useful. combinatorics.org/ojs/index.php/eljc/article/view/v8i1r40/pdf | |
| Mar 8, 2020 at 16:10 | comment | added | darij grinberg | I think Bridget Tenner is someone worth asking about this (or at least looking into her papers). | |
| Mar 8, 2020 at 16:09 | comment | added | darij grinberg | The support of a permutation can also mean the set of all of its non-fixed points. That is a different set. | |

| Mar 8, 2020 at 11:01 | comment | added | Mare | @ChristianStump I guess "Support cardinality" might be a good name for this statistic, but maybe there is already a name for this used in some textbook/article that might be even shorter. | |
| Mar 8, 2020 at 10:41 | comment | added | Christian Stump | Just looking at St000019: what is wrong with cardinality of support ? | |
| Mar 8, 2020 at 10:31 | comment | added | Christian Stump | Q1: I have seen $\{i_1,\dots,i_l\}$ being called support of $\pi$ as it is independent of the chosen word the Matsumoto's property that all reduced expressions are connected by braid relations. | |
