| Mar 24, 2013 at 18:47 | comment | added | Johannes Hahn | The $F_4 \to E_6$ embedding can be obtained by a process of "folding" at least at the level of Weyl groups. I'm pretty certain that this should be possible for lie algebras as well. In essence $\mathfrak{f}_4$ should be the space of fixed points under the diagram automorphism of $\mathfrak{e}_6$. | |
