Hi Richard: In the beginning I had two more given digits. I tried to find out if the puzzle is still solvable by taking out two more digits without distruction of the symmetrie. Well, it was! ;-))

During testsolving I did not need heavy T&E. Actually I only needed it twice and the solution is unique.

But you are right, I raised the difficulty to four stars.

Hi Luigi, I think you forgot a few given digits...
;-)
I already quit because of too heavy T&E. :-(
