Flag-transitive block designs and unitary groups

Seyed Hassan Alavi, Mohsen Bayat, Ashraf Daneshkhah

In this article, we study $2$ -designs with $g cd (r, λ) = 1$ admitting a flag-transitive automorphism group. The automorphism groups of these designs are point-primitive of almost sim…

Flag-transitive block designs with prime replication number and almost simple groups

Seyed Hassan Alavi, Mohsen Bayat, Jalal Choulaki +1

In this article, we study $2$ -designs with prime replication number admitting a flag-transitive automorphism group. The automorphism groups of these designs are point-primitive of…

Symmetric designs and four dimensional projective special unitary groups

Seyed Hassan Alavi, Mohsen Bayat, Asharf Daneshkhah +1

In this article, we study symmetric $(v, k, λ)$ designs admitting a flag-transitive and point-primitive automorphism group $G$ whose socle is $P S U_{4} (q)$ . We prove that there exis…
