Suppose that A, B and S are non-empty subsets of a finite abelian group G with| G|> 1. Then the generalized restricted sumset A+ S B:={a+ b: a∈ A, b∈ B, a− b∉ S} contains at least min{| A|+| B|− 3| S|, p (G)} elements, where p (G) is the least prime factor of| G|. Further, we also have| A+ S B|≥ min{| A|+| B|−| S|− 2, p (G)}, provided that both| A| and| B| are large with respect to| S|.
