We analyze the superconformal index of the  = 3 supersymmetric generalized orientifold theories recently proposed. In the large N limit we derive the index from the Kaluza–Klein modes in AdS 5 × S 5 / Z k , which are obtained from ones in AdS 5 × S 5 by a simple Z k projection. For the ordinary Z 2 orientifold case the agreement with the gauge theory calculation is explicitly confirmed, and for Z k ≥ 3 we perform a few consistency checks with known results for  = 3 theories. We also study…
