摘要 具有良好传递性的区组设计是代数组合学研究的一个重要领域.1993年,Cameron和Praeger证明了不存在区传递8-设计.2013年,龚罗中和刘伟俊证明了不存在指数不超过5的区传递7-设计.本文在此基础上证明了不存在指数不超过10的区传递7-设计. The block designs with good transitivity is an important research field of algebraic combinatorics. In 1993, Cameron and Praeger proved that there is no block transitive 8 - designs. In 2013, Gong and Liu proved that there is no block transitive 7 - designs with index A ~〈 5. This paper proves that there is no block transitive 7 - designs with index λ≤10.
