Our institute network uses authenticated proxy. I am having trouble
installing a package using
*sage -i* OR *sage -f* from command-line. I am using sage-4.7.2 on Ubuntu
12.04 (development branch).
I just tried to install *sage-mode*. The error is:
Deleting directories
OK I found few things, I thought I'll write it here to be recorded in
the history. First of all, sage is happy with this:
quoKer = F2.Subgroup([F2.1^4, F2.2^2, (F2.1 *F2.2)^2])
myD4 = F2/quoKer
But, I'll end up with an error from Gap that I'm generating more than
25 cosets. Basically the quot
Hi there,
I would like to make a finite group using gen/relation. As far as I
read my only chance is to use the Gap wrapper. So I can make the
group, I can also make the subgroup but the '/' of Gap doesn't work in
sage. So what's the wrapper function for that '/' notation:
F2 = gap.FreeGroup(a, b

In this case sage does not complaint, but check_irreducible is not
intended for this use, but to avoi

Thanks a lot! :)
It looks like I really should improve my searching skills. Usually

I get the following strange result:
(289.5750, 289.6170, -0.02800200)
My question is: where do those low order digits come from? And how can
I get rid of them?
When you are performing numerical computations on a computer, you always
have an imprecision due to

Hello!
I have discovered a strange (at least so it seems to me) behaviour
of Sage. Here is the problem:
I have a list of tuples of the following format:
(2000, 289.4280)
(2001, 289.5570)
(2002, 289.6050)
(2003, 289.6170)
