Hi I'm new to sage. Can you tell me how to construct finite fields using quotient of poly ring? For instance suppose I want to construct GF(5^2) using a GF(5) poly ring mod out by x^2 + x + 1 how do I do that? I can construct the quotient like this:
p = 5 F = GF(p) R.<x> = F['x'] f = x * x + x + 1 S = R.quotient(f, 'a') How do I force S to a field so that I can use it with elliptic curves? I know that I can simply do GF(5^2) but I want to be able to specify the modulus explicitly. Thanks. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
