hi there,
sorry if this is not really sage-related (it is in a way).
So David, i'm currently reading your book "adventures in group
theory", and i'm thoroughly enjoying it. I'm sure it will also be of
great help when i finally teach sage in my university (the switch from
maple is about to happen
1. How can I expand (a + b + c + d)^4 in Sage?
2. How can I see all my notebooks in Sage?
I have a few notebooks. However, I do not remember their names.

Using Sage 3.3 you can do this:
sage: a, b, c, d = var("a b c d")
sage: expand((a + b + c + d)^4)
d^4 + 4*c*d^3 + 4*b*d^3 + 4*a*d^3 + 6*c^2*d^2 + 12*b*c*d^2 +
12*a*c*d^2 + 6*b

Uhm, click on "Home" at the top row menu? If that's not what you want
please be more specific.

To implement M_R in Sage would be non-trivial, since it
is a pair of moves followed by a solid cube rotation.
The rotation changes *all* the moves which follow it.
So to implement X*M_R*Y (reading left-to-right) in Sage
you'd have to change Y.
I've done it in a few cases to check moves but it is
I'm doing a long computation in Sage and I'd like to be able to print

of an algorithm.
If I use the print command, then such information will accumulate and

I see! In a sense i was sort of right. Now
Some times we need input a lot of data, for estadistics analisys
Can I get automaticly data from MySql DataBase?

Yes--you can install any Python package that interacts with MySQL
right in Sage's Python environment. Just type "sage -sh" first and
then install it (via setup.py or easy_install) just as you would in
any other Python environment. Then you can import it and use it from
all your scripts.

Sage includes SQLAlchemy
http://www.sqlalchemy.org/
which provides a Sage interface to mysql.

Hi Dave:
Once you have your zero-dimensional ideal K within a Sage ring, you
could try the variety() command
K.variety(ring=QQbar) or
K.variety(ring=CC)
to get its solutions as algebraic numbers or complex floating point
numbers, respectively. See 'variety()' under
http://www.sagemath.org/doc
Hum... I talked to my colleague again today and convinced him to give
SAGE a try and to produce the animation using ffmpeg.
Now the question is: in sage is it possible to save the sequences of
images as a batch process (verses saving them one-by-one by hand)?
Also he wonders if it possible to s
