I believe the 2025-11-13 hard puzzle has 1 solution, not 34 #1
Description
Hi!
I've also been writing a pips solver and been looking at your solution counts to see whether we come up with the same numbers. I think the 2025-11-13 hard puzzle actually has just 1 solution, not the 34 that README.md currently states.
It's very possible I'm wrong! Combinatorial search is tricky and it's easy to write bugs. If you indeed believe there are 34 solutions, or even > 1 solution, it would be very nice to see them.
Of course, no pressure or obligation -- I understand if you've moved on from this project or have other things to do :)
Thank you for your work!
