Shift method

 

Use this method to construct odd magic squares which are no multiple of 3 (= 5x5, 7x7, 11x11, 13x13, 17x17, ... magic squares). To construct an 17x17 magic square, the first row is 0-a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p (fill in 1 up to 16 instead of a up to p; that gives 16x15x14x13x12x11x10x9x8x7x6x5x4x3x2 = 2,09228 * 1013 possibilities).

 

To construct row 2 up to 17 of the first grid shift the first row of the first grid each time two places to the left. To construct row 2 up to 17 of the second grid shift the first row of the second grid each time two places to the right.

It is possible to shift this 17x17 magic square on a 2x2 carpet of the 17x17 magic square and you get 288 more solutions .

 

Instead of shift 2 to the left and shift 2 to the right, you can also shift 3, 4, 5, 6 or 7 to the right and/or to the left (e.g. in the first grid shift 5 to the left and in the second grid shift 3 to the left ór 3 to the right). In total you can construct all 2,30254 x 1031 panmagic 17x17 squares.
