Hi Juan,
I'm trying to use subs method in PolynomialSequence, but when I doing that
I get the same PolynomialSequence. For example in code below my polynomial
sequence PS has only one polynomial (P) ... I'm trying to use subs but I
get the same polynomial. Where is wrong?
The thing is that

I want to solve polynomial equations and in order to do so, I do
something like:
sage: R.x,y = PolynomialRing(QQ, order='lex')
sage: I = R.ideal([x*y-1, x^2-y^2])
sage: I.groebner_basis()
[x - y^3, y^4 - 1]
Meanwhile, I found, which seems to do

It is because your first curve E1 is not a minimal model. Its label
is still successfully given ('7161g1') but when you construct the
curve from that label it gives you the minimal model. Compare
discriminants: that of E1 is 2^12 times that of E2.
I am copying to sage-support and sage-nt,
