Certain balanced incomplete block designs are such that a double grouping of blocks into sets made up of complete replications is possible, with a corresponding reduction in the variance of interblock ...

Several important series of balanced incomplete block designs can be derived from orthogonal factorial designs. One is the series on balanced lattice of Yates (1936); refer to page 396 of Cochran and ...
