<h3>
Description:
</h3>
The finite field with <tt> p</tt>^{<tt> k</tt>} elements
is created and stored in <tt> O</tt>. This routine
differs from <tt> FunFF</tt> in that it only allows one
way of generating the field; however, it has the
advantage that one can work relatively.

<h3>
Example:
</h3>

<pre>

kash> O:=OrderMaximal(Poly(Zx,[1,0,-4,0,1]));
Generating polynomial: x^4 - 4*x^2 + 1
Discriminant: 2304 

kash> FFCreate(O, 3, 4);
> Finite field of size 3^4
