Hi There, I want to factor a polynomial in GF(2^3).
After I started GAP, I type the following commands (with outputs): gap> f := GF(8); GF(2^3) gap> y := Indeterminate(f); x_1 gap> pol := y^7 + Z(2)^0; x_1^7+Z(2)^0 gap> Factors(pol); [ x_1+Z(2)^0, x_1^3+x_1+Z(2)^0, x_1^3+x_1^2+Z(2)^0 ] However, I expect the result to be all the non-zero elements in GF(2^3). What am I missing? (How can I evaluate p for Z(2^3)^2, for instance?) Your time, effort and suggestions will be greatly appreciated Jaco _______________________________ Jaco Versfeld Lecturer Centre for Telecommunications Access and Services School of Electrical and Information Engineering University of the Witwatersrand Johannesburg Tel: +27-11-717-7212 Email: jaco.versf...@wits.ac.za web: http://dept.ee.wits.ac.za/~versfeld <html><p><font face = "verdana" size = "0.8" color = "navy">This communication is intended for the addressee only.
