Block Designs

Recall our blanket assumption that all block designs are binary: this means that no treatment occurs more than once in a block, so that the blocks are sets rather than general multisets. However, it can happen that the same set occurs more than once in the list of blocks; that is, the list of blocks may be a multiset. In this case we say that the design has repeated blocks.
