Constructions of tight sets of the Hermitian polar space $\mc{H}(2r-1,q^2)$

Alice M. W. Hui, Weicong Li, Qing Xiang +1

In this paper, we construct two infinite families of tight sets with parameters and , respectively, in the Hermitian polar space $\mathcal{H}(2r…

On codes in the projective linear group

Tao Feng, Weicong Li, Jingkun Zhou

In this paper, we resolve a conjecture of Green and Liebeck [Disc. Math., 343 (8):117119, 2019] on codes in . To be specific, we show that: if is a dihedral subgroup…

A construction of minimal linear codes from partial difference sets

Ran Tao, Tao Feng, Weicong Li

In this paper, we study a class of linear codes defined by characteristic functions of certain subsets of a finite field. We derive a sufficient and necessary condition for such a…

The point regular automorphism groups of the Payne derived quadrangle of

Tao Feng, Weicong Li

In this paper, we completely determine the point regular automorphism groups of the Payne derived quadrangle of the symplectic quadrangle , odd. As a corollary, we show t…

On the existence of O'Nan configurations in Buekenhout unitals in PG(2,q^2)

Tao Feng, Weicong Li

In this paper, we establish the existence of O'Nan configurations in all nonclassical ovoidal Buekenhout-Metz unitals in .
