Defined in `fff'.
-
An irreducible univariate polynomial of degree d is returned.
-
If an irreducible trinomial x^d+x^m+1 exists, then the one
with the smallest m is returned.
Otherwise, an irreducible pentanomial x^d+x^m1+x^m2+x^m3+1
(m1>m2>m3 is returned.
m1, m2 and m3 are determined as follows:
Fix m1 as small as possible. Then fix m2 as small as possible.
Then fix m3 as small as possible.
