A construction of 2-arc-transitive non-solvable covers of complete graphs
Jiyong Chen, Cai Heng Li, Ci Xuan Wu +1
We construct connected -arc-transitive covers of complete graphs with non-abelian characteristically simple transformation groups. This solves the existence problem for non-solv…
The finite -set homogeneous graphs
Cai Heng Li, Fu-Gang Yin, Jin-Xin Zhou
A classification is given of finite -set-homogeneous graphs for , leading to a striking result that each finite -set-homogeneous graph is -homogeneous. It sh…
A complete classification of solvable factors of almost simple groups
Tao Feng, Cai Heng Li, Conghui Li +3
We give an explicit characterization of solvable factors in factorizations of finite classical groups of Lie type. This completes the classification of solvable factors in factoriz…
Factorizations of almost simple orthogonal groups of plus type
Cai Heng Li, Lei Wang, Binzhou Xia
This is the fifth one in a series of papers classifying the factorizations of almost simple groups with nonsolvable factors. In this paper we deal with orthogonal groups of plus ty…
Locally Finite Vertex-Rotary Maps and Coset Graphs with Finite Valency and Finite Edge Multiplicity
Cai Heng Li, Cheryl E. Praeger, Shu Jiao Song
It is well-known that a simple -arc-transitive graph can be represented as a coset graph for the group . This representation is extended to a construction of -arc-transiti…
The graphs with a symmetrical Euler cycle
Jiyong Chen, Cai Heng Li, Cheryl E. Praeger +1
The edges surrounding a face of a map form a cycle , called the boundary cycle of the face, and is often not a simple cycle. If the map is arc-transitive, then there…
