This page gives all the binary connected block designs (up to isomorphism) with v points, b blocks, constant replication number r and constant block size k, such that v,b,r,k>=2 and v+b<=18. The lists of designs for given (v,b,r,k) are in DTRS external representation protocol version 3.0 format, compressed by bzip2. Each file has content types i, c, g and s, which mean that each design in these files has, respectively, <indicators>, <combinatorial_properties>, <automorphism_group> and <statistical_properties> subtrees. Moreover, each file has content type a, which means that all binary connected block designs (up to isomorphism) with the given (v,b,r,k) are in that file. In addition, all equivalence classes of resolutions of these designs (when they are resolvable) are given.
