hello: I want to make a field, such as Q(2^(1/3), 2^(1/3)i), where Q is Rationals, and i^2=-1.
I am fail to describe 2^(1/3) and 2^(1/3) i. 2^(1/3) does not work. i is E(4), and Q(2^(1/3))=Q[x]/(x^3-2), but how to describe 2^(1/3)i ? Can gap help me to find out the minimal polynomial of 2^(1/3) i ? thanks. _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
