Block designs and systems of pairs

Combinatorics 2026-07-20 v1

Abstract

We propose a new way to construct one block design from another, thus linking some block designs in a new way. At the same time, we find relationships between block designs and systems of pairs. Some of these relationships are established, another one is conjectured.
