Nine palace grid we have played, nine palace grid a total of several solutions?

Open classification of magic square matrix: Science, mathematics, mathematical model, what is magic square? For example, the figure on the right is a magic square, that is, n * n (n > = 3) numbers are put into the n * n grid, so that the numbers in each row, column and diagonal of the grid are equal. I have been very interested in this for a long time, and I have gained a lot
