[sage-support] klein quartic symmetry group

2010-10-22 Thread andrew ewart
What is the best way of writing out code to calculate the symmetry group of the Klein Quartic (The klein quatric is the set of the solutions to f=0, where f is the polynomial x^3*y+y^3*z+z^3+x in QQ[x,y,z]) I know of 2 symmetry types one is the rotation of terms of order 3 ( (x,y,z), (z,x,y),

[sage-support] Creating large matrix hangs

2010-10-22 Thread Cary Cherng
I have a sage script that ultimately creates a python list called MMv of length 35354. Each element is a list of length 55. This is in effect a 35354 by 55 matrix. Print statements show that when I run my script with load two.sage it gets stuck at taking this list and creating a matrix. I am using
