Block designs with $g cd (r, λ) = 1$ admitting flag-transitive automorphism groups

Seyed Hassan Alavi, Mohsen Bayat, Mauro Biliotti +12

In this paper, we present a classification of $2$ -designs with $g cd (r, λ) = 1$ admitting flag-transitive automorphism groups. If $G$ is a flag-transitive automorphism group of a non-…

Classification of flag-transitive primitive symmetric $(v, k, λ)$ designs with $P S L (2, q)$ as socle

Shenglin Zhou, Delu Tian

Let $D$ be a nontrivial symmetric $(v, k, λ)$ design, and $G$ be a subgroup of the full automorphism group of $D$ . In this paper we prove that if $G$ acts flag-tran…
