    Added this fact mentioned by John Baez here:

    The Dynkin diagram of E 6E_6 has 2-fold symmetry, corresponding to a outer automorphism of order 2. E 6E_6 acts on the octonionic projective plane and its nontrivial outer automorphism gives rise to a projective duality in its geometry.

    Used unicode subscripts for indices of exceptional Lie groups including title and links. When not linked, usual formulas are used. See discussion here. Links will be re-checked after all titles have been changed. (Removed two redirects for “E6” from the top and added one for “E6” at the bottom of the page.)
