long

In order to obtain the string representation of an
NumberFieldFractionalIdeal, the class group of the number field is
computed to determine whether or not the ideal is principal. This can
take a very long time. For example, the following is essentially
immediate:
{{{
sage: K.<zeta> = CyclotomicField(23)
sage: F = K.ideal(2).factor()
}}}
But now, doing
{{{
sage: F
}}}
takes a very long time.
