I am new to sage and I am trying to run the gp interface.
In gp I can define an elliptic curve e and then access j by e.j
? e=ellinit([0,-1,1,0,0]);
? e.j
%2 = -4096/11
Trying to do the same in sage I did
e=gp.ellinit([0,-1,1,0,0])
What is the syntax to return j for this e. e.j does not work nor do variations like gp.e.j that I tried -- I know that j is stored in
e[13]
but I would like to use the syntax (or something close to) e.j, or e.disc, etc that I am used to typing when working directly in gp.
I am probably missing something very simple here. Thank you for any help.
