On the lengths of MDS codes with a two-transitive permutation automorphism group

Haihua Deng, Tao Feng, Andrey V. Vasil'ev

Let $C$ be an $[n, k]_{q}$ maximum distance separable (MDS) code with $4 \leq k \leq q - 3$ , and suppose that it has a $2$ -transitive permutation automorphism group. In this paper we show t…

Algebraic degrees of quasi-abelian semi-Cayley digraphs

Shixin Wang, Majid Arezoomand, Tao Feng

For a digraph $Γ$ , if $F$ is the smallest field that contains all roots of the characteristic polynomial of the adjacency matrix of $Γ$ , then $F$ is called the splitting field of $…

A note on non-empty cross-intersecting families

Menglong Zhang, Tao Feng

The families $F_{1} \subseteq (k _{1} [ n ]), F_{2} \subseteq (k _{2} [ n ]), \dots, F_{r} \subseteq (k _{r} [ n ])$ are said to be cross-intersecting if $|F_i…
