Local data
This elliptic curve is not semistable. There are 5 primes of bad reduction:
| prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $I_{6}^{*}$ | Additive | -1 | 4 | 14 | 2 |
| $3$ | $2$ | $I_{2}$ | Split multiplicative | -1 | 1 | 2 | 2 |
| $5$ | $3$ | $I_{3}$ | Split multiplicative | -1 | 1 | 3 | 3 |
| $7$ | $3$ | $I_{3}$ | Split multiplicative | -1 | 1 | 3 | 3 |

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 |
|---|---|---|
| $2$ | 2B | 8.12.0.6 |
| $3$ | 3B | 3.4.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 14280 = 2^{3} \cdot 3 \cdot 5 \cdot 7 \cdot 17 \), index $384$, genus $5$, and generators
$\left(\begin{array}{rr} 3554 & 14259 \\ 3855 & 374 \end{array}\right),\left(\begin{array}{rr} 5879 & 14256 \\ 13428 & 13991 \end{array}\right),\left(\begin{array}{rr} 1 & 12 \\ 12 & 145 \end{array}\right),\left(\begin{array}{rr} 2872 & 21 \\ 13995 & 13906 \end{array}\right),\left(\begin{array}{rr} 12256 & 3 \\ 3621 & 14194 \end{array}\right),\left(\begin{array}{rr} 14257 & 24 \\ 14256 & 25 \end{array}\right),\left(\begin{array}{rr} 1 & 24 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 6561 & 4168 \\ 2516 & 509 \end{array}\right),\left(\begin{array}{rr} 11901 & 9524 \\ 20 & 7221 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 24 & 1 \end{array}\right),\left(\begin{array}{rr} 15 & 106 \\ 12974 & 5051 \end{array}\right)$.
The torsion field $K:=\Q(E[14280])$ is a degree-$14554402652160$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/14280\Z)$.
