Example:
</h3>

<pre>

kash> o := Order(Poly(Zx, [1 , 0, 73, -280, -2399]));
Generating polynomial: x^4 + 73*x^2 - 280*x - 2399

kash> ox := PolyAlg(o);
Univariate Polynomial Ring in x over Generating polynomial: x^4 + 73*x^2 - 280\
*x - 2399

kash> PolyAlgCoef(ox);
> Generating polynomial: x^4 + 73*x^2 - 280*x - 2399
