Abstract

We describe an alternative perspective for at least some of the subgroups in Aschbacher's class C9. Then we show that under the twisted tensor product embedding of the groups PSp2(qt) and PSp 4(qt) in orthogonal groups over GF(q), t ≥ 3, q ≥ 4 even, an intermediate embedding of type C3 occurs. © Walter de Gruyter 2007.
