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 | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $3$ | $IV^{*}$ | additive | -1 | 2 | 8 | 0 |
| $3$ | $1$ | $II$ | additive | -1 | 3 | 3 | 0 |
| $5$ | $4$ | $I_{1}^{*}$ | additive | 1 | 2 | 7 | 1 |
| $13$ | $4$ | $I_{1}^{*}$ | additive | 1 | 2 | 7 | 1 |
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 \( 390 = 2 \cdot 3 \cdot 5 \cdot 13 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 301 & 2 \\ 301 & 3 \end{array}\right),\left(\begin{array}{rr} 389 & 2 \\ 388 & 3 \end{array}\right),\left(\begin{array}{rr} 131 & 2 \\ 131 & 3 \end{array}\right),\left(\begin{array}{rr} 157 & 2 \\ 157 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 389 & 0 \end{array}\right)$.
The torsion field $K:=\Q(E[390])$ is a degree-$1811496960$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/390\Z)$.
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 | $2$ | \( 114075 = 3^{3} \cdot 5^{2} \cdot 13^{2} \) |
| $3$ | additive | $6$ | \( 16900 = 2^{2} \cdot 5^{2} \cdot 13^{2} \) |
| $5$ | additive | $18$ | \( 18252 = 2^{2} \cdot 3^{3} \cdot 13^{2} \) |
| $13$ | additive | $98$ | \( 2700 = 2^{2} \cdot 3^{3} \cdot 5^{2} \) |
