What Mestre–Nagao scores detect about ℓ-ranks of imaginary quadratic fields: small representations, moderate-height points and a residual tail (ℓ = 3, 5, 7, 11)
Searches for imaginary quadratic fields with large $\ell$-rank force classes of order $\ell$ through small representations $4m^\ell=y^2+Dz^2$ and pay one class-
