The theory of $(λ, μ)$ -fold factorizations of groups

Donald L. Kreher, Shuxing Li, Douglas R. Stinson

Motivated by recent work on $λ$ -fold near-factorizations by Kreher, Li, and Stinson (Designs, Codes and Cryptography, 2026), we introduce and systematically investigate $(λ, μ)$ -fol…

$λ$ -fold near-factorizations of groups

Donald L. Kreher, Shuxing Li, Douglas R. Stinson

We initiate the study of $λ$ -fold near-factorizations of groups with $λ > 1$ . While $λ$ -fold near-factorizations of groups with $λ = 1$ have been studied in numerous papers, this is…

Uniqueness and explicit computation of mates in near-factorizations

Donald L. Kreher, William J. Martin, Douglas R. Stinson

We show that a "mate'' $B$ of a set $A$ in a near-factorization $(A, B)$ of a finite group $G$ is unique. Further, we describe how to compute the mate $B$ very efficiently using an…

Near-factorizations of dihedral groups

Donald L. Kreher, Maura B. Paterson, Douglas R. Stinson

We investigate near-factorizations of nonabelian groups, concentrating on dihedral groups. We show that some known constructions of near-factorizations in dihedral groups yield equ…
