Hi all,
I can have a link on one worksheet to another worksheet (e.g.
http://localhost:8000/home/user/12/), but this includes the number
that sage internally gives that worksheet (here: 12). Now if I upload
these worksheets to another server, they are assigned different
numbers and the links don'
We'd like to set up a sage server allowing different users to see,
copy and edit our published worksheets. However, this allows users to
execute arbitrary system calls, e.g.
> os.popen("ps auxw").read()
The formatting of the output is not perfect, but still, this is a
problem!
I'd be grateful for

Hi,
I want to have a numerical value of a Dirichlet character :
I have this line code in my notebook:
sage:
G = DirichletGroup(21)
chi = G.1;
chi(23)
evaluate:
zeta6 - 1
And when i want to use this value: zeta6 - 1 i have the error message:
G = DirichletGroup(21)
chi = G.1;
chi(23)
B=13*chi(

This works:
sage: emb = B.parent().complex_embeddings()[0]
sage: emb(B)
-6.5 + 11.2583302492*I
B is an element of a number field:
sage: B.parent()
Cyclotomic Field of order 6 and degree 2
and number fields have several embeddings into CC (in this case, 2):
sage: len( B.parent().complex_embeddi

Dear Team,
on a linux machine with 4 Dual Core AMD Opteron(tm) Processor 270, I
had some computations with Sage 3.1.1.
One of them had a very long Singular sub process, and eventually I
killed the sub process.
By consequence, a massive amount (more than 20) of new Python
processes popped up (se

Hi,
well, I have now two different alternatives to be tested: a list of
matrices or a numpy array. since I am programming with scripts, I
should verify which of them works better in that case.
thanks for your suggestions!!

Thanks for the useful links, Martin. I downloaded and compiled the

Is it possible to calculate the derivative of a boolean polynomial in
Sage using PolyBoRi?
I can do this for polynomials over GF(2):
sage: R. = PolynomialRing(GF(2),3)
sage: f = 3*x^2*y + 2*x*y + y + 9*x^2 + 5*x - 3
sage: f
x^2*y + x^2 + x + y + 1
sage: f.derivative(x)
1
sage: f.derivative(y)

Hi,
I have a question about libsvm using under Sage. I have downloaded
libsvm (a Support Vector Machine classification library) which comes
with a python interface.
I did build the sources as follows :

A homework exercise for my students asks them to find all subgroups of
S_4, which should be a very instructive exercise, even if a bit
unreasonable. In SAGE, the conjugacy_classes_subgroups() method
gets you started, and the quick-and-dirty brute-force code below
creates all possible subgroups

In Rob's example it would be nice (and good for the students to see)
if instead of looping over all g in G to construct conjugate subgroups
he could loop over coset representatives of H in G (where H is his
representative_subgroup), or (optimal) coset reps of the normalizer of
H in G. Now we can
