Elliptic curve over real numbers
Is it possible to define an elliptic curve over the real numbers in SageMath? I want to calculate the order of a point on the curve.

What kind of reals do you want ?
One could do
sage: E = EllipticCurve_from_c4c6(AA(4),AA(5).sqrt()); E
Elliptic Curve defined by y^2 = x^3 - 1/12*x - 0.002588041640624757? over Algebraic Real Field
sage: E.point_set(AA)
Abelian group of points on Elliptic Curve defined by y^2 = x^3 - 1/12*x - 0.002588041640624757? over Algebraic Real Field
