Allan, You might try offering $100 or more for a solution, or better, say that if someone solves it you will denote $100 in their name to the OEIS. This has worked quite often in the past - go to the OEIS Foundation web page, http://oeisf.org/ , and look for "in honor of". You will see that several people have been honored in this way, several problems have been solved, freeing up people's time for other things, and the OEIS Foundation has benefitted from some modest donations! It's known as a win-win-win situation! Best regards Neil Neil J. A. Sloane, President, OEIS Foundation. 11 South Adelaide Avenue, Highland Park, NJ 08904, USA. Also Visiting Scientist, Math.

I just read the comments more carefully and find that I have asked exactly this question five years ago. I have no memory of this whatsoever. And where are my undergraduate minions? Surely I do not have to do this myself? Grump, grump.
