Just because you asked a long time ago doesn't make it less of a mathematical object!

| Apr 3, 2010 at 14:02 | comment | added | David R. MacIver | By the way, I've proven one of the other two results false (or at least, the proof is wrong), so my belief in this one is reaffirmed. It would be good to have something to reference in a bibliography though if anyone can provide one. | |
