Thankx for your quick response!!! I wish I could help, I'm weak in programming... specially in c++, but I'm trying to learn as fast as possible (~10 years according to Peter Norvig)... Anyway I will try a little bit.
About extension fields, do you mean GF(p^w) where p is prime? I though fflas-ffpack supported it, but now I don't know, I'm not sure. Looking through their code I cannot find anything about generator polynomials to construct finite fields... So I'm not sure. I asked something like that in their forum, I'm just waiting for their response. Well, I'll keep trying, Thkx a lot Christian On Nov 11, 11:01 am, Martin Albrecht <[email protected]> wrote: > On Wednesday 11 November 2009, Christian wrote: > > > Hi, > > I read that the c++ library fflas-ffpack is included in Sage, I'm > > trying to find the commands which use it, but so far I couldn't find > > them. > > > I want to implement the finite field 2^8 using fflas-ffpack. > > > With the normal commands in Sage(I guess Givaro), that would be: > > > F.<x> = GF(2)[] > > # The get the Finite Field with polynomial generator 0x11B (283) > > k.<a> = GF(2^8,name='a',modulus=x^8+x^4+x^3+x+1,repr='int') > > > Where are the commands which use fflas-ffpack to build that field? > > There is none, while FFLAS-FFPACK is included, the finite field implementation > is not wrapped in Python.
