With the alternative method of Strachey we make 4 as proportional as possible 7x7 magic squares (shift) to construct the 14x14 magic square, and than we swap numbers to get the magic square valid.
To construct the 4 panmagic 7x7 squares, take the numbers 0 up to 6 as row coordinates and take the digits 0 up to (7 x 4 -/- 1 = ) 27 as column coordinates.
7x column coordinate + 1x row coordinate + 1 = panmagic 7x7 square
