I was highly surprised yesterday. March 2020: R, x = PolynomialRing(ZZ, "x"); S, y = PolynomialRing(R, "y"); T, z = PolynomialRing(S, "z"); U, t = PolynomialRing(T, "t"); f = x + y + z + t + 1 p = f^30; @time q = p*(p+1); 20.099625 seconds (2.32 M allocations: 102.120 MiB, 0.78% gc time) Regards, __ Greg -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
