| Feb 21, 2016 at 10:00 | comment | added | Mark Grant | @RyanBudney: Is it possible that you misread the question? Most (well, at least half of) real projective spaces don't fit under any of the categories a) to c) mentioned in the question. I think it makes perfect sense to ask if Whitney's Theorem can be improved for Lie groups, say, which are parallelizable. | |
