Click HERE for the Macaulay2 we did in class on Wednesday October 5th.

In general, from a command line on a system with Macaulay2 installed, to setup Macaulay2 in emacs, type M2 and then press enter to start it. Now type "setup();" followed by enter. This should setup macaulay2 in emacs. Now start emacs (for example on a Mac, maybe aquamacs) and hit F12. This should start Macaulay2. Let me know if you need help with anything.

For some discussion on Nakayma's lemma and what it "means", see this discussion on Mathoverflow.
