8446 avoid 0^0 in number fields Robert Miller David Loeffler "In the case of a trivial number field, such as
{{{
K. = NumberField(polygen(QQ))
}}}
the Selmer group function doesn't work, since the generator `a` of the number field is 0, and when we're constructing polynomials we use the form `coeff*a**i`. However, if `i==0`, we get an `ArithmeticError` since Sage does not have conventions for `0^0`.
I found several places where this comes up, and I've fixed them where I can." defect closed major sage-4.4 number fields fixed John Cremona sage-4.4.alpha2 Robert Miller David Loeffler N/A
