In this talk we will consider cyclotomic srgs Cay(F_q, D) in a broader sense, namely, D is a union of cosets of a subgroup of the multiplicative group F_q^* of F_q , not just a single coset of a subgroup of F_q^*. Twelve new infinite families of srgs are obtained this way. We also show that these srgs give rise to some very interesting association schemes. This is a joint work with Tao Feng.
