Abstract:
We consider the subgroups $H$ in a symplectic or orthogonal group over a finite field of odd characteristic such that $O_r(H)\neq1$ for some odd prime $r$. We obtain a refinement of the well-known Aschbacher Theorem on subgroups of classical groups for this case.
Keywords:
Aschbacher Theorem, symplectic group, orthogonal group, radical $r$-subgroup.
