I see, just found a webpage detailing that mistake, thanks. I include the webpage for completeness: groupprops.subwiki.org/wiki/…

This approach is the one that my teacher hinted at for the test question (this is a question on a test that I did not get and am now trying to solve). Can you elaborate on how we know that $\sum_{i = 0}^k x^i$ for $k = 2,4,16$ divides $x^{255}-1$?

Ah! I read the Proposition wrongly, and the monic primes are indeed in $\Bbb F_2[x]$, I was under the wrong impression as you can see from my wording in the question. Thank you!

This answer made the most sense to me as someone who happened upon this question, for what that's worth.

Thanks for your help Dmitri! The only part I am not quite seeing is how you arrived at the last column of your basis matrix?

comment American undergraduate applying overseas
@ZhenLin From the sounds of things it is typical to do Part III then. Reading the "Unofficial Guide to Part III" by Tom K\"orner has helped, but I do have one question about number of different courses: I see that courses are either 2 or 3 units depending on how long they last, and then it is recommended you offer 17-19 credits for examination. Is this examination at the end of your year, or do you take an examination after each term?
