Local data
This elliptic curve is not semistable. There are 5 primes of bad reduction:

$2$ | $1$ | $IV$ | Additive | -1 | 2 | 4 | 0 |
$3$ | $1$ | $I_0^{*}$ | Additive | -1 | 2 | 6 | 0 |
$5$ | $2$ | $I_{2}^{*}$ | Additive | 1 | 2 | 8 | 2 |
$7$ | $2$ | $I_{6}$ | Non-split multiplicative | 1 | 1 | 6 | 6 |
$23$ | $1$ | $I_{9}$ | Non-split multiplicative | 1 | 1 | 9 | 9 |
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 \( 690 = 2 \cdot 3 \cdot 5 \cdot 23 \), index $16$, genus $0$, and generators
$\left(\begin{array}{rr} 511 & 420 \\ 15 & 571 \end{array}\right),\left(\begin{array}{rr} 3 & 4 \\ 8 & 11 \end{array}\right),\left(\begin{array}{rr} 4 & 3 \\ 9 & 7 \end{array}\right),\left(\begin{array}{rr} 664 & 435 \\ 335 & 269 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 6 & 1 \end{array}\right),\left(\begin{array}{rr} 685 & 6 \\ 684 & 7 \end{array}\right),\left(\begin{array}{rr} 413 & 0 \\ 0 & 689 \end{array}\right),\left(\begin{array}{rr} 1 & 6 \\ 0 & 1 \end{array}\right)$.
The torsion field $K:=\Q(E[690])$ is a degree-$2308331520$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/690\Z)$.
