Abstract

Abstract An oval 𝒪 of a projective plane is called two-transitive if there is a collineation group G fixing 𝒪 and acting 2-transitively on its points. If the plane has odd order, then the plane is desarguesian and the oval is a conic. In the present paper we prove that if a plane has order a power of two and admits a two-transitive oval, then either the plane is desarguesian and the oval is a conic, or the plane is dual to a Lüneburg plane.
