The results below are complete, since the LMFDB contains all elliptic curves with conductor norm at most 100000 over imaginary quadratic fields with absolute discriminant 4
Note: The completeness Only modular elliptic curves are included

not known for all curves in the database; curves for which these are
unknown will not appear in searches specifying one of these
quantities.
