comment Is there a finite set of primes such that if K over Q is completely split at all those primes then it is Q?
This is a great answer emphasizing many number-theory results. Thanks!

comment Examples of non-split algebraic groups
@user76758 - I was sloppy but I thought there is no confusion, since Humphreys' comment said minimally but I edited the question. Could you suggest a reference where I can find about unit groups of CSAs that you mention? (PS: $E\cap E'$ is ill-posed too :) )

Keerthi: Sorry for the error, I really meant $v \not\in S$. Also could you give a reference for the statement "For almost all p, G has a smooth reductive model over Z_p". Thanks.

Thanks Prof. Humphreys, I edited the question - yes, in both cases.

comment Modern Mathematical Achievements Accessible to Undergraduates
This cannot possibly be correct because it doesn't add up modulo 10. But yes, Elkies has results in a similar flavor.
