That's what I thought. I wrote some code with Algorithm::Combinatorics and it took bloody forever so I knew it had to be wrong. I like the idea of constrained search, with all 9 entries summing to multiple of 3, but the problem is the arrangement of the PAUL letters can be anywhere in the grid, so I'm stuck searching permutations anyway.
Thanks for your input!
