11 hours ago | comment | added | dhy | You can rephrase this as looking for the automorphisms of $E$ which preserve the degree $3$ line bundle coming from the embedding of $D$ into $\mathbb{P}^2.$ If $E$ is generic then its automorphism group is generated by translations and multiplication by $-1$ and you can explicitly check that the subgroup preserving $L$ is generated by $3$-torsion points and multiplication by $-1$. | |
