Local data at primes of bad reduction
This elliptic curve is not semistable. There are 4 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $I_{4}^{*}$ | additive | -1 | 4 | 12 | 0 |
| $5$ | $1$ | $II^{*}$ | additive | 1 | 2 | 10 | 0 |
| $19$ | $1$ | $I_{5}$ | nonsplit multiplicative | 1 | 1 | 5 | 5 |

Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$.
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 4028 = 2^{2} \cdot 19 \cdot 53 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 2757 & 2 \\ 2757 & 3 \end{array}\right),\left(\begin{array}{rr} 4027 & 2 \\ 4026 & 3 \end{array}\right),\left(\begin{array}{rr} 2281 & 2 \\ 2281 & 3 \end{array}\right),\left(\begin{array}{rr} 2015 & 2 \\ 2015 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 4027 & 0 \end{array}\right)$.
The torsion field $K:=\Q(E[4028])$ is a degree-$45734734356480$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/4028\Z)$.
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 |
|---|---|---|---|
| $2$ | additive | $2$ | \( 25175 = 5^{2} \cdot 19 \cdot 53 \) |
| $5$ | additive | $2$ | \( 848 = 2^{4} \cdot 53 \) |
| $19$ | nonsplit multiplicative | $20$ | \( 21200 = 2^{4} \cdot 5^{2} \cdot 53 \) |
| $53$ | nonsplit multiplicative | $54$ | \( 7600 = 2^{4} \cdot 5^{2} \cdot 19 \) |
