Block-transitive 3-designs Associated with Alternating Groups
《数学理论与应用》2024年第4期19-30,共12页Gan Yunsong Liu Weijun 
supported by the National Natural Science Foundation of China(No.12471022)。
A t-(v,k,λ)design is said to be G-point-primitive or G-block-transitive,if its automorphism group G acts primitively on the point set or transitively on the block set,respectively.In this paper we begin by extending ...

The Group of Automorphisms of Transitive 2-(v, 23, 1) Designs
《Chinese Quarterly Journal of Mathematics》2015年第4期579-586,共8页李上钊 
Supported by the National Natural Science Foundation of China(11271208,11471054);Supported by the Graduate Students’Scientific Research Innovation Project of Jiangsu Province Ordinary University(KYLX1213)
This paper is a contribution to the study of the automorphism groups of 2 - (v, k, 1) designs. Let D be a 2 - (v, 23, 1) design and G a block-transitive and point-primitive group of automorphism of D. Then the soc...

On Block-transitive 6-(v, k, λ)-Designs with k at Most 10000
《Algebra Colloquium》2014年第2期231-234,共4页Qionghua Tan Weijun Liu Jing Chen 
Supported by the National Natural Science Foundation of China (Grant No. 10871205, 11271208) and Hunan Provincial Science and Technology Department (2011FJ6092).
In recent years, there has been a great deal of research concerning the flag- transitive t-designs, however, few about the block-transitive t-designs with t large (t 〉 4). In 1993, Cameron and Praeger conjectured t...
