Cherlin's conjecture on finite primitive binary permutation groups

Submission date: 9 June 2021


A permutation group is binary if its orbits on k-tuples, for any integer k ≥ 2, can be deduced from its orbits on 2-tuples. Cherlin conjectured that a finite primitive binary permutation group G must lie in one of three known families. In this paper we complete the proof of this conjecture. To do this we study the case where the group G is almost simple of Lie type.
