Dec 31, 2009 at 1:23	comment	added	Harrison Brown		The connection with the Bernoulli numbers is well-known for K_n(Z) when n = 2 (mod 4), and I don't think it's a coincidence here either. I found an interesting-looking article by Weibel: math.uiuc.edu/K-theory/0691/KZsurvey.pdf . In general, though, I think you might be asking too much if you want "intuition," considering how notoriously strange homotopy-type stuff can be.

Dec 31, 2009 at 1:08	comment	added	Harrison Brown		Do you have a link to a list of the first however many K-groups of Z? I'm sure I've seen one somewhere, but I don't remember where.
