On the Theory of Trade off and Its Application to the Construction of BIB Designs with Variable Support Sizes.
Abstract
A BIB design with b blocks is said to have the support size b* when exactly b* of the b blocks are distinct. BIB designs with b* < b have interesting applications in design of experiments and finite population sampling. A method called trade off is introduced for the construction of BIB designs. This method is applied and some techniques in combinatorial topology to study BIB designs with arbitrary v and k = 3 in general and with v = 7 and k = 3 in particular. The existence or nonexistence of BIB designs with any given b and b* is determined except the case when b* = 16 for the family of BIB designs with v = 7 and k = 3.
