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 \( 22440 = 2^{3} \cdot 3 \cdot 5 \cdot 11 \cdot 17 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 8977 & 2 \\ 8977 & 3 \end{array}\right),\left(\begin{array}{rr} 11221 & 2 \\ 11221 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 22439 & 0 \end{array}\right),\left(\begin{array}{rr} 18361 & 2 \\ 18361 & 3 \end{array}\right),\left(\begin{array}{rr} 16831 & 2 \\ 16831 & 3 \end{array}\right),\left(\begin{array}{rr} 7481 & 2 \\ 7481 & 3 \end{array}\right),\left(\begin{array}{rr} 14521 & 2 \\ 14521 & 3 \end{array}\right),\left(\begin{array}{rr} 22439 & 2 \\ 22438 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right)$.
The torsion field $K:=\Q(E[22440])$ is a degree-$18296963334144000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/22440\Z)$.
