As a running example, if we take a 4×4 square, where the Greek and Latin terms have the values ("α", "β", "γ", "δ") = (0, 4, 8, 12) and ("a", "b", "c", "d") = (1, 2, 3, 4), respectively, then we have "α" + "β" + "γ" + "δ" = 2 ("α" + "δ") = 2 ("β" + "γ"). Similarly, "a" + "b" + "c" + "d" = 2 ("a" + "d") = 2 ("b" + "c"). This means that the complementary pair "α" and "δ" (or "β" and "γ") can appear twice in a column (or a row) and still give the desired magic sum. Thus, we can construct:
