The main result of this paper is the identification of G with PGL2(K) for some algebraically closed field K of characteristic ?2. © 2024 The Author(s)eninfo:eu-repo/semantics/closedAccessAlgebraic GroupsGroups Of Finite Morley RankNon-Standard Frobenius AutomorphismPseudofinite GroupsSmall groups of finite Morley rank with a supertight automorphismArticle2-s2.0-8518845906010.1016/j.jalgebra.2024.03.001905Q1884647
