Sorry, I should have said that x has to be the main variable. I could design some polys for which the timing didn't depend on the main variable, but for now, x has to be the main variable to see how slow this is (at least in Sage and Singular). I'm not sure if the first or last variable is x in Fricas, but if you define your polynomial ring so that the first or last variable is x, you will likely see a big slowdown. Of course Fricas may also just use a really fast algorithm. I didn't check. Bill. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
