Existence of resolvable optimal strong partially balanced designs
B. Du. Discrete Applied Mathematics 154 (2006) 930-941,-0001,():
We shall refer to a strong partially balanced design SPBD(v, b, k; λ, 0) whose b is the maximum number of blocks in all SPBD(v, b, k; λ, 0), as an optimal strong partially balanced design, briefly OSPBD(v, k, λ). Resolvable strong partially balanced design was first formulated by Wang, Safavi-Naini and Pei [Combinatorial characterization of l-optimal authentication codes with arbitration, J. Combin. Math. Combin. Comput. 37 (2001) 205–224] in investigation of l-optimal authentication codes. This article investigates the existence of resolvable optimal strong partially balanced design ROSPBD(v, 3, 1). We show that there exists an ROSPBD(v, 3, 1) for any v≥3 except v = 6, 12.
