Hi, According to this function, Is there any function in sage that element b {"b = f(x+a) - f(x)} on GF(p^n) (p is prime) must be into G, For example :
f(x) = x G = GF(2^2,'a') G.list() = {0,1,a,a+1} then f(a) - f(a+1) = -1 !!!! must be one of {0,1,a,a+1} Thx, -- 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 URL: http://www.sagemath.org
