Abstract
- We study the group T<subscript>A</subscript> of rearrangements of the airplane limit space introduced by Belk and Forrest (2019). We prove that T<subscript>A</subscript> is generated by a copy of Thompson's group F and a copy of Thompson's group T, hence it is finitely generated. Then we study the commutator subgroup [T<subscript>A</subscript>; T<subscript>A</subscript>], proving that the abelianization of T<subscript>A</subscript> is isomorphic to Z and that [T<subscript>A</subscript>; T<subscript>A</subscript>] is simple, finitely generated and acts 2-transitively on the so-called components of the airplane limit space. Moreover, we show that TA is contained in T and contains a natural copy of the basilica rearrangement group T<subscript>B</subscript> studied by Belk and Forrest (2015). [ABSTRACT FROM AUTHOR]
