      57 = 11^2 - 8^2

      8 * 8 + 57 = 11 * 11
      7 * 9 + 57 = 10 * 12
      6 * 10 + 57 = 9 * 13
      5 * 11 + 57 = 8 * 14
      4 * 12 + 57 = 7 * 15
      3 * 13 + 57 = 6 * 16
      2 * 14 + 57 = 5 * 17
      1 * 15 + 57 = 4 * 18
      0 * 16 + 57 = 3 * 19
      (-1)* 17 + 57 = 2 * 20
      (-2) * 18 + 57 = 1 * 21
      (-3) * 19 + 57 = 0 * 22
