A finite field is a field with a finite number of elements. For each prime power $q^k$, there is a unique (up to isomorphism) finite field with $q^k$ elements. Up to isomorphism, these are the only finite fields.

Finite field special functions
Taking into account Peter's Tailor analysis I can say the following.
For example we have finite field $GF(p)$ for $p$ prime;
We can take element $2$ and obtain subgroup generated by $2$: $<2>$.

Finite field special functions
I am looking for special class of involutive functions (f) with exactly one (zero) fixed point over finite field $F_q$ with properties:
1) $f(f(x))=x$ for any $x \in F_q$ , $f(x)=x$ iff $x=0$
2) F …
