Design Information

In the design the magic square is 4 x 4, so for this magic square n = 4.

For any n x n square in general the sum of the rows and columns is = 0.5n(n² + 1), hence 34.

The square in this design was in an engraving made by Albrecht Durer, and it has the numbers 15 and 14 in the bottom row, the date of the engraving.

This particular square is called a gnomom magic square, because all the rows, columns, diagonals, the 4 corner 2 x 2 squares as well, and the 2 x 2 central square, all sum to 34.

If every number in the square is subtracted from n² + 1, that is 17, you get the complementary magic square.

The Indian mathematical genius, Ramanujan, made a square from his birth date,
22 December, 1887, so his first line is 22, 12, 18, 87.
All rows sum to 139, as well as all columns, every diagonal, and every 3 x 2 square.
