R.<x> = GF(2)[]
f = x^5+x^2+1 fx = ntl.GF2X(f) gives error: Traceback (most recent call last): fx File "ntl_GF2X.pyx", line 141, in sage.libs.ntl.ntl_GF2X.ntl_GF2X.__init__ AttributeError: 'sage.rings.polynomial.polynomial_modn_dense_ntl.Po' object has no attribute '_Polynomial_dense_mod_n__poly' fx = ntl.GF2X(f.list()) works, as well as fx = ntl.GF2X(f.ntl_ZZ_pX()) (It is a shame that normal arithmetic for polys over GF(2) still seems to be implemented by the ntl ZZ_pX library, which is usually at least 10 times slower than GF2X, up to degree 2^17 anyway. In that range GF2X matches the speed of magma.) --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
