Use this method to construct odd magic squares which are no multiple of 3 (= 5x5, 7x7, 11x11, 13x13, 17x17, ... magic squares). To construct an 19x19 magic square, the first row is 0-a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r (fill in 1 up to 18 instead of a up to r; that gives 18x17x16x15x14x13x12x11x10x9x8x7x6x5x4x3x2 = 6,40237 * 1016 possibilities).
To construct row 2 up to 19 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 19 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 19x19 magic square on a 2x2 carpet of the 19x19 magic square and you get 360 more solutions .
Instead of shift 2 to the left and shift 2 to the right, you can also shift 3, 4, 5, 6, 7 or 8 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 7 to the right ór 7 to the left). In total you can construct all 3,55140 x 1036 panmagic 19x19 squares.
Use the shift method to construct magic squares of odd order from 5x5 to infinity.
