Perfect difference families, perfect systems of difference sets and their applications

Hengrui Liu, Tao Feng, Xiaomiao Wang +1

Let $v$ be a positive odd integer. A $(v, k, λ)$ -perfect difference family (PDF) is a collection $F$ of $k$ -subsets of ${0, 1, \dots, v - 1}$ such that the multiset $\bigcup_…

The existence of pyramidal Steiner triple systems over abelian groups

Yanxun Chang, Tommaso Traetta, Junling Zhou

A Steiner triple system STS $(v)$ is called $f$ -pyramidal if it has an automorphism group fixing $f$ points and acting sharply transitively on the remaining $v - f$ points. In this pa…

Existence of magic rectangle sets over finite abelian groups

Shikang Yu, Tao Feng, Hengrui Liu

Let $a$ , $b$ and $c$ be positive integers. Let $(G, +)$ be a finite abelian group of order $ab c$ . A $G$ -magic rectangle set MRS $_{G} (a, b; c)$ is a collection of $c$ arrays of size $a\t…

A family of regular polytopes of order $4 p^{m}$ with type ${p, 2 p}$

Dong-Dong Hou, Ting-Ting Kong, Hai-Peng Qu

In this paper, we construct an infinite families of group $G$ of order $4 p^{m}$ which can be an automorphism group of some regular polytope with type ${p, 2 p}$ , where $m \geq 3$ an…

Two-distance transitive normal Cayley graphs

Jun-Jie Huang, Yan-Quan Feng, Jin-Xin Zhou

In this paper, we construct an infinite family of normal Cayley graphs, which are $2$ -distance-transitive but neither distance-transitive nor $2$ -arc-transitive. This answers a que…

Stability of pair graphs

Yan-Li Qin, Binzhou Xia, Jin-Xin Zhou +1

We start up the study of the stability of general graph pairs. This notion is a generalization of the concept of the stability of graphs. We say that a pair of graphs $(Γ, Σ)$ is st…
