Dear sage-devel,
I am running into an issue with computing isogeny classes of elliptic
curves over number fields.
Here is what I entered:
K. = QuadraticField(4569)
myJ = 46969655/32768
E = EllipticCurve(j=K(myJ))
C = E.isogeny_class()
This raises a KeyError in the first instance, which seems t
t wishes,

MWE:
sage: A = -17737878703644595885728157881856/2195118875780412735240966796875

sage: E = EllipticCurve([A,B])
sage: lcalc.analytic_rank(E)
This produces "***
