Hi, I have a set of data that I want to create a contour plot for.
Since I have the data and not the function that created the data, I
cannot use contour_plot. Matplotlib has a function "contour" that
accepts a vector of data and does exactly what I want expect I cannot
get it to work in Sage note
Hi there,
just playing around this time, tried to use SAGE to compute the Weyl
group associated to the Cartan matrix
[2, -1, 0]
[-1, 2, 0]
[0, -1, 2]
that should be the usual permutation group S_4.
After obtaining the generators
s1= [-1 0 0]
[ 1 1 0]
[ 0 0 1],
s2 = [ 1 1 0]
[ 0 -1 0]
1. you can coerce the coefficients to GF(3)
2. You can try G1 = gap(G) and
G2 = gap(SymmetricGroup(4))
and G1.IsomorphismGroups(G2):
sage: s1 = [-1, 0, 0]
sage: s1 = matrix([[-1, 0, 0], [1, 1, 0], [0, 0, 1]])
sage: s2 = matrix([[1, 1, 0], [0, -1, 0], [0, 1, 1]])
sage: s3 = matrix(

I can also confirm that 4.0alpha0 builds on latest ArchLinux (had a
bit of spare time).
Kind regards,

Can I? The generators are still distinct in GF(3), but I might lose
elements when I take products (maybe not in this case, I am thinking
about the general problem for an arbitrary Weyl group). Wouldn'

I am using Robert's twist.py to try to setup a simple server. The
server side is working. I need help getting the client side to work.
I would like to have the client use a screen(form) that would allow
him to input an expression and lets say the server will calculate the
integral and return t
Although I can't try it right now, I think the main point is this:
