Law, Maska; Praeger, Cheryl E.; Reichard, Sven Flag-transitive symmetric 2-(96,20,4)-designs. (English) Zbl 1187.05087 J. Comb. Theory, Ser. A 116, No. 5, 1009-1022 (2009). The authors classify the symmetric \(2-(96,20,4)\) designs which admit a flag-transitive automorphism group. There are exactly 4 such designs.
