order 的相互正交数独拉丁方 (MOSLS) 的最大数量。在本文中,我们为 qa 素数幂构造了一组不能扩展到 MOSLS 阶的 MOSLS。这与 ordern 的普通拉丁方理论相反,其中每组相互正交的拉丁方(MOLS)可以扩展到一组 MOLS(这是最好的可能)。为了证明这一点,我们构造了一个特定的最大部分散度,并使用贝利、卡梅伦和康纳利建立的数独拉丁方和射影几何之间的联系。
The maximum number of mutually orthogonal Sudoku Latin squares (MOSLS) of orderis. In this paper, we construct for,qa prime power, a set ofMOSLS of orderthat cannot be extended to a set ofMOSLS. This contrasts to the theory of ordinary Latin squares of ordern, where each set ofmutually orthogonal Latin Squares (MOLS) can be extended to a set ofMOLS (which is best possible). For this proof, we construct a particular maximal partial spread of sizeinand use a connection between Sudoku Latin squares and projective geometry, established by Bailey, Cameron and Connelly.
