Help board

Problems the solver cannot finish, and people who can. Post yours, or take one that is still open.

No open questions right now. That is a good sign, and a quiet board.

How to get an answer

  1. Put the problem itself in the problem box, in the same form you would type into the solver. Someone can then open it there in one click.
  2. Say what you have already tried, and which step stopped you. A question that shows its working gets answered; one that only shows the problem usually does not.
  3. When a reply gets you unstuck, mark it as the answer. That is what turns your question into a page the next person can find.
