I have never studied group theory, so this is way beyond what I'm ready for. But I scanned over a few sections and read to the point that I got lost.

The part that surprised me is that it seems to focus on rational numbers. I always assumed that Galois Groups were focused on more abstract concepts of sets. Is Galois Theory mostly about rational number (or even real numbers), or is the author just using the rationals to keep the paper focused on beginners?

Intel's communication is incredibly poor. Errata exist for all CPUs but this one is quite important and resulted in no proper public communication it seems.
