@ahorn That's a good point, Indeed my choice was arbitrary. I edited my answer to reflect this.

Many thanks Jyrki, I'll need to study this a bit. I'll update later.

comment Finite field question involving the trace and a permutation.
I know a couple of people who were claiming that they could do math better after a couple of beers :) Anyway, I think I have an idea, but I have to double think before posting anything, I'm not sure yet.

comment Bijections of a finite field that preserve the kernel of the trace
I have realized what my $f(x)$ should be. Indeed, I was asking too much. If you want, check my updated question here: math.stackexchange.com/questions/1183155/…

comment Bijections of a finite field that preserve the kernel of the trace
Thank you for your clear and thorough answer, I was quite off with my conjecture about these monomials. I will have to think how/if the question can be restated to suggest some other class of polynomials.

I think I was being quite careless when I wrote that title. It should be just bijections.

comment Which powers of a primitive element of a finite field yield a generator of a finite field extension?
Thanks for your answer. Now, you say that WLOG, $i|(q^m-1)$, else $i$ is associate to a divisor's residue in $\Bbb{Z}_{q^m-1}$. Could you comment on that? I fail to understand it..
