The constructions of Singleton-optimal locally repairable codes with minimum distance 6 and locality 3

Yanzhen Xiong, Jianbing Lu

In this paper, we present new constructions of $q$ -ary Singleton-optimal locally repairable codes (LRCs) with minimum distance $d = 6$ and locality $r = 3$ , based on combinatorial stru…

Flag-transitive $2$ - $(v, k, λ)$ designs with $λ \geq (r, λ)^{2}$

Junchi Zhang, Jianbing Lu, Meizi Ou

This paper is devoted to the study of $2$ -designs with $λ \geq (r, λ)^{2}$ admitting a flag-transitive automorphism group $G$ . The group $G$ has been shown to be point-primitive of eith…

Flag-transitive point-primitive quasi-symmetric $2$ -designs and exceptional groups of Lie type

Jianbing Lu

Let $D$ be a non-trivial quasi-symmetric $2$ -design with two block intersection numbers $x = 0$ and $2 \leq y \leq 10$ , and suppose that $G$ is an automorphism group of $\math…

Flag-transitive point-primitive quasi-symmetric $2$ -designs with block intersection numbers $0$ and $y \leq 10$

Jianbing Lu, Yu Zhuang

In this paper, we show that for a non-trivial quasi-symmetric $2$ -design $D$ with two block intersection numbers $x = 0$ and $2 \leq y \leq 10$ , if $G\leq \mathrm{Aut}(\mathca…
