Homework is typically due two class periods after we finish the section. NOTE: Significant bonus points are available for proving any of the conjectures you make as a result of the computer explorations. You may not actually always have the tools in the preceding section for the proof though--sometimes later techniques may be needed. Thus, I will accept proofs of these conjectures at any time in the semester, but they must be written up especially carefully.
I asked Joe Gallian about solutions, and he said he is in the process of preparing them, and he added the following:
"Thanks for your letter. If it is not a bother I ask you to keep track of
the "solutions" you or your students produce and we can compare them to
what I come up with. Although I had a particular conjecture in mind for
each exercise there may be more than one possible."
So proofs would be very cool to send to him!

Chapter 26: 6, 9 , 13, 21 (hint--for 6, use cor to Dyck's theorem after trying to construct a group table to determine the max number of elements--note: if you get closure, you have gotten at least all of the elements, even if there is some duplication),
