Let $E$ be an elliptic curve defined over $\Q$. A prime $p$ is called a **surjective prime** for $E$ if the mod-$p$ Galois representation
\[
\rho_{E,p}: Gal(\overline{\Q}/\Q) \to \GL(2,\F_p)
\]
attached to $E$ is surjective.

Conjecturally, when $E$ does not have CM, all primes $p>37$ are surjective primes.
