construct/mc bibd: a task in MathConstructOptimize-Envs-harbor (Harbor dataset). A balanced incomplete block design BIBD(13, 4, 3) is a collection of b = 39 blocks, each a set of 4 distinct points from {0, 1, ..., 12}, such that every pair of distinct points is contained in exactly 3 of the blocks…
The task
A balanced incomplete block design BIBD(13, 4, 3) is a collection of b = 39 blocks, each a set of 4 distinct points from {0, 1, ..., 12}, such that every pair of distinct points is contained in exactly 3 of the blocks (consequently every point lies in exactly r = 12 blocks). The same block may appear more than once.
