Local data at primes of bad reduction
This elliptic curve is not semistable. There are 2 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $7$ | $2$ | $I_0^{*}$ | additive | -1 | 2 | 6 | 0 |
| $11$ | $1$ | $I_{1}$ | split multiplicative | -1 | 1 | 1 | 1 |
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 |
|---|---|---|
| $5$ | 5B.4.2 | 25.60.0.2 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 3850 = 2 \cdot 5^{2} \cdot 7 \cdot 11 \), index $1200$, genus $37$, and generators
$\left(\begin{array}{rr} 38 & 41 \\ 1291 & 1089 \end{array}\right),\left(\begin{array}{rr} 2640 & 1659 \\ 2877 & 1863 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 50 & 1 \end{array}\right),\left(\begin{array}{rr} 3801 & 50 \\ 3800 & 51 \end{array}\right),\left(\begin{array}{rr} 1 & 50 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1649 & 0 \\ 0 & 3849 \end{array}\right),\left(\begin{array}{rr} 1436 & 2345 \\ 3815 & 2416 \end{array}\right)$.
The torsion field $K:=\Q(E[3850])$ is a degree-$39916800000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/3850\Z)$.
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 |
|---|---|---|---|
| $7$ | additive | $26$ | \( 11 \) |
| $11$ | split multiplicative | $12$ | \( 49 = 7^{2} \) |
