Having an uneven number of toes. odd permutation 奇蹄的有奇数个脚趾的【数】奇排列,奇置换
The method of creating odd rank concentric magic square was acquired by the character and transform of determinant in this paper, Many forms of any odd rank magic square can be created by the method and permutation and combination. 利用行列式的性质和变换得到了构造奇数阶同心幻方原基的一种方法,利用这种方法和排列组合都能得到任意奇数阶幻方的多种形式。
