box o' numbers  aha:!

arrange the numbers 1 to 8 in the grid below such that adjacent numbers are not in adjacent boxes (horizontally, vertically, or diagonally).

       ___
      | 1 |
  =============
  | 6 | 4 | 3 |
  =============
  | 2 | 7 | 5 |
  =============
      | 8 |
      =====

the arrangement above, for example, is wrong because 3 & 4, 4 & 5, 6 & 7, and 7 & 8 are adjacent.
