Hi!
I found the following issue:
sage: R.=PowerSeriesRing(QQ)
sage: f=u+O(u,v,t,T)^200
sage: g=f-u
sage: g(u^4,v^4,t^4,T^4)

For the record, here's what I get with Maxima 5.28.0. I think
to_poly_solve has been updated in the not so distant past so maybe Sage
is using
Please, could you explain more what is the problem.
According to my understand. b and c are two parameters and you want to
solve for d.
and you try to use grobner basis, but what I know grobner basis for
polynomial and this is not polynomial because the square root. So , you can
write d=y^2, y^2==b
