A geometric characterization of the perfectRee-Tits generalized octagons
Published online by Cambridge University Press: 01 January 1998
Abstract
Given a generalized octagon which satisfies certain geometric conditions, we show that it must be isomorphic to the Ree--Tits octagon arisingnaturally from a Ree group of type $^2F_4$ over a perfect field of characteristic 2, in which the Frobenius automorphism has a square root.
