On twisted tensor product group embeddings and the spin representation of symplectic groups
2007
Advances in Geometry
Preserved Fulltext
We describe an alternative perspective for at least some of the subgroups in Aschbacher's class C 9 . Then we show that under the twisted tensor product embedding of the groups P Sp 2 (q t ) and P Sp 4 (q t ) in orthogonal groups over GF (q), t ≥ 3, q ≥ 4 even, an intermediate embedding of type C 3 occurs.
