关于一类不完全Hanani三元系的存在性Keywords: Hanani三元系, 不完全, 嵌入, 可分组设计Hanani triple systems, incomplete, embedding, group divisible designs Abstract: 设v≡1 mod 6. 一个阶为v的Hanani三元系是一个Steiner三元系,且满足所有区组可以划分成(v-1)/2个大小为(v-1)/3的部分平行类和1个大小为(v-1)/6的部分平行类. Hanani三元系被视作Kirkman三元系的自然推广. 本文研究Hanani三元系的嵌入问题,我们将完全确立洞大小为7的不完全Hanani三元系的存在性.Let v≡1 mod 6. A Hanani triple system of order v(HATS(v))is an STS(v)satisfying that all the blocks can be partitioned into(v-1)/2 partial parallel classes of size(v-1)/3 and one partial parallel class of size(v-1)/6. A HATS is regarded as a generalization of Kirkman triple system. In this paper,we consider the embeddings of HATS and establish completely the existence of IHATS(v,7)
