New description:
Older version of Sage was able to say when it couldn't compute Galois
group. However, in 5.4,
{{{
NumberField(x^21-2, 'a').galois_group(type="pari").order()
}}}
gives answer 252, but with
{{{
NumberField(x^22-2, 'a').galois_group(type="pari").order()
}}}
I got
{{{
Error, the variable '_s_' must have a value
}}}
I guess this relates to kash interface.
