I agree that simply rotating the entire puzzle 90º or 180º doesn't count as a different solution. That makes the total number of puzzle permutations less than the number I calculated above, but I'm not sure how much less. It may simply be that number divided by 4, but that seems too simple of a solution. In any case, I at first assumed that my program had merely produced a rotated version of the same solution, but the program output showed that the puzzle piece in the bottom center of igmd's image, was placed in the top left in my solution, and there is no rotational transformation which can move a center edge piece to a corner. I then assumed I had fumbled in encoding the puzzle in my program, so I sliced and diced and pasted the puzzle pieces to correspond to my solution and everything fit. Here is igmd's solution again: and here is my solution rotated 90º to the left: and it is indeed a different solution. So it is now a find the difference puzzle. Ready, set, go!

Watering the front garden yesterday, after days of no watering and extremely hot temps. The only thing that looked bad was the last petunia. Bought some soil today so I could move one or two flowers as the African marigolds are huge, as are the zinnias, and are squeezing out the little purple flowering plant in the middle of them. I can't remember the name.
