A Generalization of Combinatorial Designs Related to Almost Difference Sets

Abstract

In this paper we study a certain generalization of combinatorial designs related to almost difference sets, namely the tt-adesign, which was coined by Cunsheng Ding in 2015. It is clear that 22-adesigns are a kind of partially balanced incomplete block design which naturally arise in many combinatorial and statistical problems. We discuss some of their basic properties and give several constructions of 22-adesigns (some of which correspond to new almost difference sets, and others of which correspond to new almost difference families), as well as two constructions of 33-adesigns. We also discuss some basic properties of their incidence matrices and codes.
