In this article, we continue to study the existence of large sets of partitioned incomplete Latin squares (LSPILS). We complete the determination of the spectrum of an LSPILS ( g n ) and prove that there exists an LSPILS ( g n ) if and only if g 1 , n 3 , and ( g , n ) ( 1 , 6 ) . We also start the investigation of LSPILS with two group sizes and prove that there exists an LSPILS + ( g n ( 2 g ) 1 ) for all g 1 and n 3 except possibly for n 2 , 10 ( mod 12 ) and n 14 . Furthermore, we obtain a pair of orthogonal LSPILS + ( 1 p 2 1 ) s, where p is a prime and p 1 ( mod 6 ) .

关于大量分区的不完整拉丁方的进一步结果

在本文中,我们将继续研究大范围的分区不完整拉丁方(LSPILS)的存在。我们完成了对一个光谱的确定 LSPILS G ñ 并证明存在 LSPILS G ñ 当且仅当 G 1个 ñ 3 , 和 G ñ 1个 6 。我们还开始对具有两个小组规模的LSPILS进行调查,并证明存在一个 LSPILS + G ñ 2个 G 1个 对所有人 G 1个 ñ 3 除了可能 ñ 2个 10 国防部 12 ñ 14 。此外,我们获得一对正交 LSPILS + 1个 p 2个 1个 s,在哪里 p 是素数 p 1个 国防部 6
