(In reply to Diagonals by Penny)

Dear Penny,

When my puzzle was in the queue, awaiting approval, one of our Journeymen announced that it had four solutions.

After I asked him whether he had considered the constraint of the two long diagonals, he admitted that he had missed it. He then declared that the solution was unique and gave it the TU.

If you can find a different solution, where the numbers 1 to 9 appear in both of the main diagonals, please will you show it to me?

Thanks,

Josie
