I will try to keep a diary/schedule of the topics we cover in the class and roughly the sections that they correspond to in the text. S = Segan the Symmetric Group, N = Class notes.
The "Labs" that are referred to below are just Maple worksheets which will have programs and examples which we discuss in class.  These can be found on the 'Computer Lab' page.
