That's it, more or less. I came across a question consisting solely of the task, yet found it rather interesting. So I gave it a try, but failed. I am thinking about adding this attempt to the question, to eventually get some people look into it. Do there exist any guidelines on that?
As Asaf suggested: post your own question. Since you are the one who's really interested in it, you should also be the one deciding which answer gets accepted, etc.
Do include a link to the question, stating that it is a source of your question, and adding what you have found about it so far.
