I'm not sure what 3d plot you want. However, if I read the documentation
at the link you provided correctly then
sage: E = pari(['1', 'I'])
sage: E.ellwp(1+I)
-1/2*I
says p(1+i)=-i/2 for the elliptic curve associated to Z+iZ.
Maybe you want to plot the real and imaginary parts of

Hi:
Either a bug in combinat.py's permutations, or an indication that
it needs to be rewritten. (permutations is a GAP wrapper which
I might have written, so should probably fix ...)

, it seems that eigenspaces uses (b). I wonder if there is any
support for adding an option to eigenspaces to use (a).

Some students can't install the SAGE software due to
inexperience with computers, so I wanted to give them
the option of using sage.math instead.

Hello David,
I installed sage 2.8.6 from source on a new install of 64 bit ubuntu 7.10.
The installation manual says

Dear sage-support team,
i'm trying to convince my boss about using modern linear algebra
software (as part of a project on group cohomology rings). However, i
need better arguments. Perhaps you have some?
This is separate from your question,
More details might help.
What is your operating system?
Did you compile the program or are you running a binary?
Is this a fresh install or did you do some hacking with the source code?

Can you try Ctl-C, Ctl-C (twice in rapid succession)

It turns out there is a draft of a document which does
what you want. You can ask there for the url of the latest

This is the right place but I don't think what you want is implemented.
The commands and examples are here:

It would be some work but possibly you could do what you could in SAGE,
then use GAP's NormalBase command?

Something like this seems like a really good idea.
My thought with the hierarchical tags is that
I'm told it will be in 2.8.3, whose release is planned
