Abstract：
We generalize the infinitesimal transformations obtained in the Ernst fields of vacuum previously to the including electromagnetic fields to form a larger infinite symmetric group which is isomorphic to the Virasoro group without a central term.Wherein we find a subgroup,the enlarged Cosgrove group.It is pointed out that new solutions of the electronic fields can be genereated from old ones by means of our new transformations.
