Odd squares: For the 3×3 odd square, since "α", "β", and "γ" are in arithmetic progression, their sum is equal to the product of the square's order and the middle term, i.e. "α" + "β" + "γ" = 3 "β". Thus, the diagonal sums will be equal if we have "β"s in the main diagonal and "α", "β", "γ" in the skew diagonal. Similarly, for the Latin square. The resulting Greek and Latin squares and their combination will be as below. The Latin square is just a 90 degree anti-clockwise rotation of the Greek square (or equivalently, flipping about the vertical axis) with the corresponding letters interchanged. Substituting the values of the Greek and Latin letters will give the 3×3 magic square.
