| May 15, 2012 at 11:46 | comment | added | Vít Tuček | The group $E_6$ is the group of collineations (aka projective transformtions) of $\mathbb{OP}^2$ while the group $F_4$ is the group of isometries since there is a naturally defined Riemannian metric on $\mathbb{OP}^2$. | |
| Jan 5, 2010 at 23:42 | comment | added | Jason DeVito - on hiatus | I believe that the automorphism group of OP^2 is F_4, as F_4/Spin(9) = OP^2 (though I'm VERY not certain about this). More on exactly what OP^2 is can be found here: mathoverflow.net/questions/1922/… | |
