added tag to bump this, I'd rather see this on front page than TeX edits of resolved qns
Aug 3, 2013 at 19:33 comment added Thomas Tam @HenryCohn: Thank you for your concern. We were indeed considering such possibilities, but now the problem seems quite difficult so we have already changed our minds. Even we do not have the answer so far! Therefore it is now purely out of curiosity.
Aug 3, 2013 at 14:34 comment added Henry Cohn Is this problem actually under consideration for a contest? (I'm not sure whether "We think this problem can be set for some math competitions for college students" was hypothetical.) If so, posting it on the internet seems risky. The students may not find it in time to have any impact on the contest, but I bet they'll find it by web searches afterwards, in which case they will wonder whether anyone got an unfair advantage.
Aug 3, 2013 at 6:10 comment added Theo Johnson-Freyd Hi Thomas: I think this is a good question. Math.SE is a better site for it, because the question is not, strictly speaking, about research mathematics. But it's not far off. To my non-expert eye, this looks like a problem in matroids, not vector spaces.
