Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$.
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 17160 = 2^{3} \cdot 3 \cdot 5 \cdot 11 \cdot 13 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 1 & 1 \\ 17159 & 0 \end{array}\right),\left(\begin{array}{rr} 10297 & 2 \\ 10297 & 3 \end{array}\right),\left(\begin{array}{rr} 2641 & 2 \\ 2641 & 3 \end{array}\right),\left(\begin{array}{rr} 12871 & 2 \\ 12871 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 8581 & 2 \\ 8581 & 3 \end{array}\right),\left(\begin{array}{rr} 11441 & 2 \\ 11441 & 3 \end{array}\right),\left(\begin{array}{rr} 7801 & 2 \\ 7801 & 3 \end{array}\right),\left(\begin{array}{rr} 17159 & 2 \\ 17158 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[17160])$ is a degree-$6121410527232000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/17160\Z)$.
