WebFor a proper BIB design, Fisher’s inequality b ≥ υ, or equivalently r ≥ k, holds. A BIB design is said to be symmetric if υ = b, and consequently r = k. Such a design is called a symmetric (υ, k, λ) design, and λ(υ − 1) = k(k − 1). A necessary condition for the existence of a symmetric (υ, k, λ) design is given by the ...
