The following is a question asked to me these days by Gülin Ercan. --

Let $G = L(q^f)$ be a finite simple group of Lie type,
and let $L(q) \cong H < G$ be the group of fixed points
of the automorphisms of $G$ induced by field automorphisms.
In case $H$ is nonsolvable -- can there exist a nontrivial
subgroup $N$ of $G$ which is normalized by $H$ and which
has trivial intersection with $H$?
