Hello,
I'm sory for repeating the same post 2 times (associativity...)

First let me say that I am a sage-newbie. I work at a high-school in
Sweden as a math teacher. Our curriculum states that we are to teach
our students in the using of computer programs when solving math
problems.
My problem is that our technicians (sp?) have succeded in installing
sage at an

As far as I know you cannot check associativity in this naive way.
For a start, nowhere in your code do you use the equation of the
curve. If that is (say) y^2=x^3+a*x+b, then your equation will only
be correct modulo the relations y1^2=x1^3+a*x1+b and so on.
However, even with that I don't

Thanks Paul, I was too lazy to try that myself. Now I am puzzled by
what I remembered being possible and impossible, but never mind -- we
have answered the original question!

Hi,
I tried the Sage 2.9.2 vmware for Windows version (downloaded from
www.sagemath.org), and it does not seems to have the jmol 3d graphics

There must surely be a simple answer to this problem, but I have not
been able to figure it out. I loop through i,j print the list
[i,j], and append the list to pts. However, once appended to points
something goes wrong, and all that points sees are the

Your problem seems to be that when you put something in a list, python
does not make a copy of it, but instead stores that actual object in the
list. So the line
pts.append(P)
appends the object P (or,
This indeed fixes the problem, and clarifies some other things for me
as well.
Thanks for your quick response Jonathan.
