Combinatorial Topology and the Trade Off Method in Bib Designs

1980
When two BIB designs based on the same set of varieties have identical parameters, one can obtain either of them from the other by trading off some blocks for an equal number of blocks. Define a trade to be two collections of blocks such that each of the (v/2) pairs of varieties is contained in the same number of blocks from both collections. A method,
