Symmetries of biplanes

Seyed Hassan Alavi, Ashraf Daneshkhah, Cheryl E Praeger

In this paper, we first study biplanes $D$ with parameters $(v, k, 2)$ , where the block size $k \in {13, 16}$ . These are the smallest parameter values for which a classifica…

Almost simple groups of Lie type and symmetric designs with $λ$ prime

Seyed Hassan Alavi, Mohsen Bayat, Ashraf Daneshkhah

In this article, we investigate symmetric $(v, k, λ)$ designs $D$ with $λ$ prime admitting flag-transitive and point-primitive automorphism groups $G$ . We prove that if $G$ …
