(22, 33, 12, 8, 4)-BIBD, an Update

  • G. H. J. van Rees


A (v, b,r, k, λ)-balanced incomplete block design is a family of b sets (called blocks) of size k whose elements (varieties) are from a v-set, v > k, such that every element occurs exactly r times and every pair exactly λ times. A (22, 33, 12, 8, 4)-BIBD is the set of parameters with the smallest v for which it is not known whether a BIBD exists or not. A survey of what is known about such a design is given.
