<h3>
Example:
</h3>

<pre>

kash> O := Order(Z,2,3);
Generating polynomial: x^2 - 3

kash> Ox := PolyAlg(O);
Univariate Polynomial Ring in x over Generating polynomial: x^2 - 3

kash> f := Poly(Ox,[1,0,Elt(O,[1,4]),Elt(O,[3,4]),9]);
x^4 + [1, 4]*x^2 + [3, 4]*x + 9
kash> PolyNorm(f);
> x^8 + 2*x^6 + 6*x^5 - 29*x^4 - 90*x^3 - 21*x^2 + 54*x + 81
