Abstract
The R_{2,2N} theories are an infinite family of non-Lagrangian SCFTs which appear in the strong-coupling limit of SU(2N+1) gauge theories with hypermultiplets symmetric and antisymmetric tensor representations. These theories are particularly interesting as they are known to arise in class S as compactifications of the A_{2N} (2,0) theories in the presence of outer-automorphism twists. These twists are particularly subtle, and only partial progress has been made towards a systematic classification of all theories which arise from this twisted sector. The flavor symmetry group is an S-duality invariant used in such a classification. We use the superconformal index to test a recent conjecture for the global form of the Sp(2N) x U(1) flavor symmetry group of the R_{2,2N} theories.
