- Bruck–Ryser–Chowla_theorem abstract "The Bruck–Ryser–Chowla theorem is a result on the combinatorics of block designs. It states that if a (v, b, r, k, λ)-design exists with v = b (a symmetric block design), then: if v is even, then k − λ is a square; if v is odd, then the following Diophantine equation has a nontrivial solution: x2 − (k − λ)y2 − (−1)(v−1)/2 λ z2 = 0.The theorem was proved in the case of projective planes in (Bruck & Ryser 1949). It was extended to symmetric designs in (Ryser & Chowla 1950).".
