Re : Field inclusion problem

I tried that and obtained the following output :


? nffactor(polynomial_called_b,polynomial_called_a)
  ***   at top-level: nffactor(polynomial_ca
  ***                 ^--------------------
  *** nffactor: incorrect polynomial in rnf function.
  ***   Break loop: type 'break' to go back to GP

I suppose itâs no use to do a âmy_field=nfinit(polynomial_called_b)â first ? The computation would be prohibitively long.
