New description:
If P is a 'kolyvagin_point' created from an elliptic curve, the doc string
says
{{{
Definition: P.kolyvagin_cohomology_class(self, n=None)
Docstring:
INPUT:
* n -- positive integer that divides the gcd of a_p and p+1 for
all p dividing the conductor. If n is None, choose the
largest valid n.
}}}
In fact, if "n" is None, a ValueError is thrown.
