Recognizing PGL$_3$ via generic 4-transitivity

Tuna Altınel[1] and Joshua Wiscons

(1) Université Claude Bernard Lyon 1, France

We show that the only transitive and generically 4-transitive action of a group of finite Morley rank on a set of Morley rank 2 is the natural action of PGL$_3$ on the projective plane.

Keywords: Primitive permutation groups, multiple transitivity, finite Morley rank
