Abstract: Langlands’ beyond endoscopy proposal for establishing functoriality motivates the study of irreducible subgroups of GL that stabilize a line in a given repesentation of GL . Such subgroups are said to be detected by the representation. In this paper we continue our study of the important special case where the representation of GL is the triple tensor product representation ⊗ . We prove a family of results describing when subgroups isomorphic to classical groups of type B , C , D are detected. n n n n n 2 n 3
