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-…

Block-transitive two-designs based on grids

Seyed Hassan Alavi, Ashraf Daneshkhah, Alice Devillers +1

We study point-block incidence structures $(P, B)$ for which the point set $P$ is an $m \times n$ grid. Cameron and the fourth author showed that each b…
