Abstract
Suppose that  V  is a finite dimensional vector space over a finite field of characteristic 2,  G  is the symplectic group on  V  and  a  is a non-zero vector of  V.  Here we classify irreducible subgroups of  G  containing a certain subgroup of $O_2(\operatorname{Stab}_G \langle a \rangle)$ all of whose non-trivial elements are 2-transvections.
