## Next homework

The next homework set has been posted to the course website. Four problems as usual. This set builds on quite a few of the techniques we have learnt so far, so there’s going to be considerable work involved. Those taking the course for credit are urged to begin working on these problems right away.

## The first homework set

It is ready at last! I have posted it to the course website (scroll down all the way). Future homework sets will be announced here as and when they get posted.

Problem 2 on this set refers to the finite field . If you are unfamiliar with this object, read this Wikipedia article. That already gives you enough information for now. If you want to learn more about finite fields, stop by my office sometime or pick up a suitable Mathematics textbook.
