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.6.1 | 7.24.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 892920 = 2^{3} \cdot 3 \cdot 5 \cdot 7 \cdot 1063 \), index $96$, genus $2$, and generators
$\left(\begin{array}{rr} 223231 & 119070 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 8 & 5 \\ 91 & 57 \end{array}\right),\left(\begin{array}{rr} 595279 & 0 \\ 0 & 892919 \end{array}\right),\left(\begin{array}{rr} 1 & 14 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 240241 & 119070 \\ 848295 & 833491 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 14 & 1 \end{array}\right),\left(\begin{array}{rr} 892907 & 14 \\ 892906 & 15 \end{array}\right),\left(\begin{array}{rr} 446461 & 119070 \\ 505995 & 833491 \end{array}\right),\left(\begin{array}{rr} 178583 & 0 \\ 0 & 892919 \end{array}\right),\left(\begin{array}{rr} 669691 & 565530 \\ 0 & 414571 \end{array}\right)$.
The torsion field $K:=\Q(E[892920])$ is a degree-$948018715544172625920$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/892920\Z)$.
