This page gives all the binary connected MV-optimal block designs (up to isomorphism) with v points, b blocks and constant block size k, such that v,b,k>=2 and v+b<=16. The lists of designs are in DTRS protocol version 3.0 format, compressed by bzip2. Each file has content type a, which means that all MV-optimal binary connected block designs (up to isomorphism) with the given (v,b,k) are in that file, where MV-optimal means having the least maximum pairwise-variance amongst the binary connected block designs with the same (v,b,k). The block-list of each given design is lexicographically least in its isomorphism class, and within each file, the designs are ordered in increasing lexicographic order of their block-lists. Each file also has content types i, c, g and s, which mean that each design in that file has, respectively, <indicators>, <combinatorial_properties>, <automorphism_group> and <statistical_properties> subtrees. In addition, all equivalence classes of resolutions of the designs are given.
