The IOP must be carefully typed,
but diagrams may be hand-drawn.
For the typesetting, one possibility
is the (free)
At all times have a paper copy you can hand-in; I do
Print out a copy each day, so that you always have the latest version to
hand-in; this, in case your printer or computer fails.

Please follow the guidelines on the

Our Teaching Page
has useful information for students in all of my classes.
It has my schedule,

are like nitroglycerin, in that one little mis-step leads to the whole
thing blowing up in your face.
There is no partial credit when it comes to Explosives and Quantifiers.
In all of my courses,
attendance is absolutely required
(excepting illness and religious holidays).
In the unfortunate event that you miss a class, you are
responsible to get all
Notes / Announcements / TheWholeNineYards
from a classmate, or several.
All my classes have a
Knocking impeachment hearings off the front page of the entertainment section,
the nifty two-tone
now has complete solns. Eager, energetic students studied them in detail…
- A useful reference is
Group Notes (pdf).
Burnside's lemma and
its application to
We dicussed in class the
commutator of two elements
in a group.

on page 2, together with Operations on Sets.
- Our TicTacToe-ish
Home-B was pictorial, and now has solns.
It wouldn't surprise me if you are curious about
Enumerating TTT-automorphisms for 4x4,
and the reasoning involved.
While we're on this topic,
I'm looking for suggestions on clever names for some of the
4x4 TTT-automorphism pictures.
The nifty Class-B
now has all solns. Please go over it in detail.
- Our thought-provoking
has complete solns.
Wikipedia page on permutations
is useful, as is
that the order of a subgp divides the order of the enclosing group.
old notes on permutations
use different convensions from what Gallian and we are using
this semester, but I want to refer to it in class today.
The thrilling Class-A
now has complete solns.
- In order to facilitate for students posting solns to our Archive,
in addition to Gallian, we will use
Abstract Algebra: Theory and Applications by
Thomas Judson (2016 Edition),
an online text made publicly available by its author. Students will be posting solns
both from their edition of Gallian, as well as Judson text, as well as any interesting
algebra problems students create.
Here is the first posting assignment for the weekend of Sept. 7,8.
Our Algebra syllabus/calendar.
- Does Zero = One? (pdf).
Here are some
proofs poofs about which
you can post to our Archive.

which we will use in class frequently.
- [Old] You looked at this
to see what you might want to review.
As the semester progresses, you will also need to print-out a few pages of
handouts that I have prepared for you.
We will cover some material that is not in our text; in
particular, applications of group-theory for solving certain
games and puzzles.
Our textbook is
