Jeet Roy 6 years, 6 months ago

In recreational mathematics and combinatorial design, a magic square[1] is a {\displaystyle n\times n} n\times n square grid (where n is the number of cells on each side) filled with distinct positive integers in the range {\displaystyle 1,2,...,n^{2}} {\displaystyle 1,2,...,n^{2}} such that each cell contains a different integer and the sum of the integers in each row, column and diagonal is equal.[2] The sum is called the magic constant or magic sum of the magic square. A square grid with n cells on each side is said to have order n.
