We improve the constructions of S. Bagchi and B. Bagchi for Steiner 2-designs which are point-regular over the additive group of a Galois ring. As a consequence, we get new cyclotomic conditions leading to point-regular Steiner 2-designs with block size $k \in {7,9,11,13,17}$.

Abstract
We improve the constructions of S. Bagchi and B. Bagchi for Steiner 2-designs which are point-regular over the additive group of a Galois ring. As a consequence, we get new cyclotomic conditions leading to point-regular Steiner 2-designs with block size $k \in {7,9,11,13,17}$.File in questo prodotto:
