The task
A balanced incomplete block design BIBD(9, 3, 3) is a collection of b = 36 blocks, each a set of 3 distinct points from {0, 1, ..., 8}, 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.
