I did notice another bug, which is that factor doesn't recognize float exponents (or rather, there are generally several issues with float exponents). For example, factor(x**3.0 + x) doesn't get factored. Am I correct in assuming that this will not get fixed by switching generators? If it is al

This sort of problem can be solved by identifying the generator with the smallest power. In this case `g = x**1/2` so `sqrt(x) + x -> y + y**2` which factors as `y*(1 + y) -> sqrt(x)*(1 + sqrt(x))`. /c On Friday, February 24, 2023 at 3:58:37 AM UTC-6 atharv@gmail.com wrote: > Lack of abili
