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 |
---|---|---|
$3$ | 3B | 3.4.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 330 = 2 \cdot 3 \cdot 5 \cdot 11 \), index $16$, genus $0$, and generators
$\left(\begin{array}{rr} 3 & 4 \\ 8 & 11 \end{array}\right),\left(\begin{array}{rr} 4 & 3 \\ 9 & 7 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 6 & 1 \end{array}\right),\left(\begin{array}{rr} 325 & 6 \\ 324 & 7 \end{array}\right),\left(\begin{array}{rr} 54 & 269 \\ 275 & 219 \end{array}\right),\left(\begin{array}{rr} 327 & 328 \\ 320 & 323 \end{array}\right),\left(\begin{array}{rr} 263 & 324 \\ 129 & 311 \end{array}\right),\left(\begin{array}{rr} 1 & 6 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 211 & 6 \\ 303 & 19 \end{array}\right)$.
The torsion field $K:=\Q(E[330])$ is a degree-$114048000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/330\Z)$.
