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 \( 7912 = 2^{3} \cdot 23 \cdot 43 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 5935 & 2 \\ 5935 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 7911 & 0 \end{array}\right),\left(\begin{array}{rr} 3957 & 2 \\ 3957 & 3 \end{array}\right),\left(\begin{array}{rr} 7911 & 2 \\ 7910 & 3 \end{array}\right),\left(\begin{array}{rr} 6537 & 2 \\ 6537 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 6625 & 2 \\ 6625 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[7912])$ is a degree-$684802555379712$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/7912\Z)$.
