"WebFisher's Inequality Theorem - [Fisher's Inequality] In a (v,k,λ)-design, b ≥ v. Proof: Suppose that b < v and let A be the incidence matrix of the design. We can add v – b columns of 0's to A to get a v × v matrix B. Since these extra columns of 0's will not alter the inner products, we must have AAΤ = BBΤ. By taking determinants we see ...
