In this note, we give a self-contained proof of the following classification (up to conjugation) of finite subgroups of GSpn(Fl) containing a nontrivial transvection for l ≥ 5, which can be derived from work of Kantor: G is either reducible, symplectically imprimitive or it contains Spn(Fl). This result is for instance useful for proving ‘big image’ results for symplectic Galois representations.
