But since this doesn't seem to be forthcoming, I'll go ahead. Aug 14 comment Sufficient conditions for ultracharactericity If K is any group, then N = K x {e} is a normal subgroup of G = K x K, with quotient G/N isomorphic to K. But N cannot be ultracharacteristic unless K is trivial, since G/(K x {e}) and G/({e} x K) are isomorphic. So the only condition that references G/N alone and that guarantees N to be ultracharacteristic is "G/N is trivial". Aug 9 awarded Supporter Aug 9 comment How do you prove that a prime is the sum of two squares iff it is congruent to 1 mod 4? Dear Matt: yes, I agree. The content is there, but (it seems to me) it's hard to see that it's there unless one already knows another argument in some more theoretical context!
