Regular, and (bi-)rotary Hall Cayley maps
Wendi Di, Zheng Guo, Cai Heng Li
A classification is given of regular, rotary, and birotary Cayley maps of which the vertex number is coprime to the valency. The classification is involved in constructions of new…

Hall Skew-morphisms and Hall Cayley maps of finite groups
Wendi Di, Zheng Guo, Cai Heng Li
A characterization is given of finite groups that have skew-morphisms of order coprime to the order , and their skew-morphisms. A complete classification is then given of…

On central difference sets in Suzuki -groups of type
Wendi Di, Zhiwen He
In this paper, when the order of is even, we prove that there exists no central difference sets in and establish some non-existence results of central partial differ…
