Galois representations

The $\ell$-adic Galois representation has maximal image for all primes $\ell$ except those listed in the table below.

prime $\ell$	mod-$\ell$ image	$\ell$-adic image
$7$	7B.6.2	7.24.0.3

The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level $1092 = 2^{2} \cdot 3 \cdot 7 \cdot 13$, index $96$, genus $2$, and generators

$\left(\begin{array}{rr} 736 & 735 \\ 903 & 358 \end{array}\right),\left(\begin{array}{rr} 1 & 14 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 484 & 735 \\ 441 & 358 \end{array}\right),\left(\begin{array}{rr} 727 & 0 \\ 0 & 1091 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 14 & 1 \end{array}\right),\left(\begin{array}{rr} 8 & 5 \\ 91 & 57 \end{array}\right),\left(\begin{array}{rr} 1079 & 14 \\ 1078 & 15 \end{array}\right),\left(\begin{array}{rr} 919 & 114 \\ 462 & 187 \end{array}\right)$.

The torsion field $K:=\Q(E[1092])$ is a degree-$2536095744$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/1092\Z)$.
