*Hello,* *I have the following defined:* p=3700001 Fp=GF(p) E=EllipticCurve([Fp(3),Fp(5)]) j_inv=E.j_invariant() l=13#Atkin prime n=((l-1)/2).round() r=2# Phi_13 factorize in factors of degree 2 s=12#Psi_13 factorize in factors of degree 12 Fps=GF(repsq(p,s),'a') a=Fps.gen() Fpr=GF(repsq(p,r),'b') b=Fpr.gen() FFps.<X>=PolynomialRing(Fps) FFpr.<x>=PolynomialRing(Fpr) EP=x^6 + (973912*b + 2535329)*x^5 + (416282*b + 3608920)*x^4 + (686636*b + 908282)*x^3 + (2100014*b + 2063451)*x^2 + (2563113*b + 751714)*x + 2687623*b + 1658379 A1.<theta>=Fpr.extension(EP)
*and now I want to "add" to A1 the square root of theta^3+3*theta+5.* *The problem is that when I consider the following:* gamma2=theta^3+3*theta+5 AA1.<xbar>=PolynomialRing(A1) AA.<gamma>=A1.extension(xbar^2-gamma2) (xbar^2-gamma2).roots(AA,multiplicities=False) it gives me a NotImplementedError. Any idea? Thank you in advance. *Irene* -- You received this message because you are subscribed to the Google Groups "sage-support" group.
