Can you find 11 simultaneous 11-queens solutions? I wrote a little app to search for them. There are regular solutions (each row shifted), but I'm looking for one that is more interesting. Maybe it doesn't exist? Press the button and see if you can find it :) mathgrrl.com/simultaneous...

here is an example of a regular solution (p.s. if you previously used this app then you may need to "hard reload" your browser to see the new search button)

tbh i think one could probably write a proof that the only 11x 11-queens solutions rae regular like this, but it's more fun to search for a non-regular one, at least for now :)
