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 | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $III$ | additive | 1 | 3 | 4 | 0 |
| $11$ | $2$ | $I_{2}$ | split multiplicative | -1 | 1 | 2 | 2 |
| $13$ | $1$ | $I_{1}$ | split multiplicative | -1 | 1 | 1 | 1 |
| $19$ | $2$ | $I_{3}^{*}$ | additive | -1 | 2 | 9 | 3 |
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 \( 494 = 2 \cdot 13 \cdot 19 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 1 & 1 \\ 493 & 0 \end{array}\right),\left(\begin{array}{rr} 287 & 2 \\ 287 & 3 \end{array}\right),\left(\begin{array}{rr} 457 & 2 \\ 457 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 493 & 2 \\ 492 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[494])$ is a degree-$9680186880$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/494\Z)$.
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 | $2$ | \( 4693 = 13 \cdot 19^{2} \) |
| $11$ | split multiplicative | $12$ | \( 37544 = 2^{3} \cdot 13 \cdot 19^{2} \) |
| $13$ | split multiplicative | $14$ | \( 31768 = 2^{3} \cdot 11 \cdot 19^{2} \) |
| $19$ | additive | $200$ | \( 1144 = 2^{3} \cdot 11 \cdot 13 \) |
