In this article, we consider an extension of automorphisms of a subfactor to the symmetric enveloping algebra introduced by Popa. We discuss the relation between this extension and invariants of automorphisms introduced by Kawahigashi. We also compute the symmetric enveloping algebras arising from orbifold subfactors.
