Is there such a thing as a "perfect" sudoku grid? By perfect I mean one in which both the long diagonals also contain the digits 1 - 9. Has anyone seen a posted grid that satisfies this condition?

I've seen this type in magazines. Also the "latin squares" variant, where each shape contains 1-9 as well as both long diagonals.
