Comment:
I fixed the first two issues as suggested (for the second issue, I used
that because that's how conjugate *currently* computes its answer for
cyclotomic fields, but you're right taking the inverse is *significantly*
quicker for large N). For the third issue, I've amended the code (what I
had done was quite silly...) to use the list of divisors sorted in reverse
order. For the final issue, I actually find it more readable the way I did
it. To each their own I guess!
