Abstract Let G= O p′(G¯ F) be a finite simple group of Lie type defined over a field of characteristic p, where F is a Steinberg endomorphism of the ambient simple algebraic group G¯. Let T¯ be an F-stable maximal torus of G¯ and set N= N G (T¯). A conjecture due to Vdovin asserts that if G≇ L 3 (2) then N∩ N x is a p-group for some x∈ G. In this paper, we use a combination of probabilistic and computational methods to calculate the base size for the natural action of G on G/N, which allows us to prove a stronger, and suitably modified, version of Vdovin's conjecture.
