Abstract

Frame difference families, which can be obtained via a careful use of cyclotomic conditions attached to strong difference families, play an important role in direct constructions for resolvable balanced incomplete block designs. We establish asymptotic existences for several classes of frame difference families. As corollaries new infinite families of 1-rotational (pq+1,p+1,1)-RBIBDs over \mathbbF_p⁺ × \mathbbF_q⁺ are derived, and the existence of (125q+1,6,1)-RBIBDs is discussed. We construct (v,8,1)-RBIBDs for v∈\624,1576,2976,5720,5776,10200,14176,24480\, whose existence were previously in doubt. As applications, we establish asymptotic existences for an infinite family of optimal constant composition codes and an infinite family of strictly optimal frequency hopping sequences.
