 the irreducible polynomial - each bit represents a term in the polynomial.
 Therefore there will either be three or five bits set dependent on whether the
 polynomial is a trinomial or a pentanomial.
+In either case, B<a> and B<b> represents the coefficients a and b from the

 EC_group_get_curve() obtains the previously set curve parameters.
