On The Smallest Non-Trivial Action Of Saut(Fn) For Small N, Reemon Spector
Rose-Hulman Undergraduate Mathematics Journal
In this paper we investigate actions of SAut(Fn), the unique index 2 subgroup of Aut(Fn), on small sets, improving upon results by Baumeister--Kielak--Pierro for several small values of n. Using a computational approach for n ⩾ 5, we show that every action of SAut(Fn) on a set containing fewer than 20 elements is trivial.
