Activities this week

Yesterday I finished theorem 9.8 about representing a permutation as a product of disjoint cycles. In addition I did some small things about the number of k-cycles and the order of a composition of cycles.

I also did the exercises indicated on Ark2.

On friday we shall do even and odd permutations, the alternating groups and proceed with section 10. That lecture will be given by Nadia Larsen - I'll will go to a funeral.

For norwegian speakers I have also posted some notes about permutations.
