Abstract

Let v ≥ 5 and A be positive integers and let DD(v,k,λ) denote the packing number of a directed packing with block size 5 and index λ. The values of DD(v, 5, λ) have been determined for λ = 1,2 with the possible exceptions of (v, λ) = (15,1) (19,1) (27,1), [7,8, 19]. In this paper we determine the values of DD(v, 5, λ) for all v ≥ 5 and λ ≥ 3 except possibly (v, λ) = (43,3).
