N2 - A (ν, κ, λ) packing design of order ν, block size κ, and index λ is a collection of κ-element subsets, called blocks, of a ν-set V such that every 2-subset of V occurs in at most λ blocks. The packing problem is to determine the maximum number of blocks in a packing design. Packing with λ=2 is called bipacking. In this paper we solve the bipacking problem in the case κ=5 and ν≡13 (mod 20).
