摘要: 研究了强对称自正交对角数独, 引申了Lorch的构造方法, 利用有限域上的线性空间理论给出了基本构造, 证明了\emph{:} 对所有奇素数$p$,存在一个$p^2$ 阶强对称自正交对角数独.
关键词: 数独拉丁方自正交强对称对角    
Abstract: Strongly symmetric self-orthogonal diagonal Sudoku square is investigated. The construction used by Lorch is extended via linear space over finite field, and a construction of such a Sudoku square is obtained. It is proved that a strongly symmetric self-orthogonal diagonal Sudoku square of order $n$ exists when $n$ is an odd prime integer.
Key words: Sudoku square    Latin square    self-orthogonal    strongly symmetric    diagonal
