By the definition ,
U(n)={a:a<nandgcd(a,n)=1}
Hence to U(n) is the collection of all positive integers m less than such that m is coprime to n.

If S is a set of functions from X to Y then I can consider the action of a group G on S via its action on X and Y by the formula (gf)(x)=gf(g1x),
So we are considering left actions both on X and Y.

Consider Fp, the algebraic closure of Fp. I want to see that: for every proper subfield KFp,FpK is not a finite extension.
It is known that, and can be somewhat easily shown that Fp=n1Fpn.
Now, if any of the proper subfields have the form Fpn, it is easy enough to see that FpFpn(α1,,αm) for some αi by going high up enough, i.e, to some big enough m such that αiFpmFp
The problem is characterizing the proper subfields. Is every subfield of Fp going to have this form? Can we have an infinite intermediate subfield?

I think the statement is correct. But why do we have to write: [G,G]NN here instead of just G,GN?
