Shift method

 

Use this method to construct magic squares of odd order which are no multiple of 3 (= 5x5, 7x7, 11x11, 13x13, 17x17, ... magic squares). To construct an 11x11 magic square, the first row is 0-a-b-c-d-e-f-g-h-i-j (fill in 1 up to 10 instead of a up to j; that gives 10x9x8x7x6x5x4x3x2 = 3.628.800 possibilities).

 

To construct row 2 up to 11 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 11 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 11x11 magic square on a 2x2 carpet of the 11x11 magic square and you get 120 more solutions .

 

Instead of shift 2 to the left and shift 2 to the right, you can also shift 3, 4 or 5 to the right and/or to the left (e.g. in the first grid shift 3 to the right and in the second grid shift 4 to the left ór 4 to the right). In total you can construct all 89.227.651.645.440.000 panmagic 11x 11 squares (= more than 89 milion x billion possibilities).

 

 

Use the shift method to construct magic squares of odd order from 5x5 to infinity.
