Local data at primes of bad reduction
This elliptic curve is not semistable. There are 3 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $4$ | $I_{4}$ | split multiplicative | -1 | 1 | 4 | 4 |

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 | $\ell$-adic index |
|---|---|---|---|
| $2$ | 2Cn | 2.2.0.1 | $2$ |
| $3$ | 3B.1.2 | 3.8.0.2 | $8$ |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 516 = 2^{2} \cdot 3 \cdot 43 \), index $96$, genus $2$, and generators
$\left(\begin{array}{rr} 480 & 511 \\ 425 & 47 \end{array}\right),\left(\begin{array}{rr} 163 & 514 \\ 114 & 503 \end{array}\right),\left(\begin{array}{rr} 259 & 12 \\ 6 & 73 \end{array}\right),\left(\begin{array}{rr} 7 & 12 \\ 450 & 403 \end{array}\right),\left(\begin{array}{rr} 5 & 2 \\ 478 & 501 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 12 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 12 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 505 & 12 \\ 504 & 13 \end{array}\right)$.
The torsion field $K:=\Q(E[516])$ is a degree-$160199424$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/516\Z)$.
The table below list all primes $\ell$ for which the Serre invariants associated to the mod-$\ell$ Galois representation are exceptional.
| $\ell$ | Reduction type | Serre weight | Serre conductor |
|---|---|---|---|
| $2$ | split multiplicative | $4$ | \( 16641 = 3^{2} \cdot 43^{2} \) |
| $3$ | additive | $2$ | \( 3698 = 2 \cdot 43^{2} \) |
| $43$ | additive | $674$ | \( 18 = 2 \cdot 3^{2} \) |
