An Essay on the Ree Octagons

  • M. Joswig
  • H. Van Maldeghem


We coordinatize the Moufang generalized octagons arising from the Ree groups of type 2F4. In this way, we obtain a very concrete and explicit description of these octagons. We use this to prove some results on suboctagons, generalized homologies, Suzuki-Tits ovoids and groups of projectivities of the Ree octagons. All our results hold for arbitrary Ree octagons, finite or not.
