为了写起来方便,我们把幻方写成矩阵的形式: 其中a_(ij)对于不同的足指数ij,分别等于从1到n~2中不同的自然数。我们知道,一般幻方的定义是(a)每行、每列的数字之和为一常数P。(b)两主对角线上数字之和也都等于P。在这里,我们将讨论一种具有下列性質的
For ease of writing, we write magic squares in the form of a matrix: where a_(ij) is equal to the different natural number from 1 to n~2 for different foot index ij. We know that the general definition of magic square is (a) the sum of the numbers of each row and each column is a constant P. (b) The sum of the numbers on the two main diagonals is also equal to P. Here we will discuss a kind of
