Local data at primes of bad reduction
This elliptic curve is not semistable. There are 5 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $1$ | $I_{13}$ | nonsplit multiplicative | 1 | 1 | 13 | 13 |
| $3$ | $2$ | $I_{2}^{*}$ | additive | -1 | 2 | 8 | 2 |
| $5$ | $1$ | $I_{7}$ | nonsplit multiplicative | 1 | 1 | 7 | 7 |

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 \( 520 = 2^{3} \cdot 5 \cdot 13 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 519 & 2 \\ 518 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 41 & 2 \\ 41 & 3 \end{array}\right),\left(\begin{array}{rr} 417 & 2 \\ 417 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 519 & 0 \end{array}\right),\left(\begin{array}{rr} 261 & 2 \\ 261 & 3 \end{array}\right),\left(\begin{array}{rr} 391 & 2 \\ 391 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[520])$ is a degree-$9661317120$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/520\Z)$.
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 |
|---|---|---|---|
| $2$ | nonsplit multiplicative | $4$ | \( 70785 = 3^{2} \cdot 5 \cdot 11^{2} \cdot 13 \) |
| $3$ | additive | $8$ | \( 1210 = 2 \cdot 5 \cdot 11^{2} \) |
| $5$ | nonsplit multiplicative | $6$ | \( 28314 = 2 \cdot 3^{2} \cdot 11^{2} \cdot 13 \) |
| $7$ | good | $2$ | \( 28314 = 2 \cdot 3^{2} \cdot 11^{2} \cdot 13 \) |
| $11$ | additive | $32$ | \( 1170 = 2 \cdot 3^{2} \cdot 5 \cdot 13 \) |
| $13$ | split multiplicative | $14$ | \( 5445 = 3^{2} \cdot 5 \cdot 11^{2} \) |

Growth of torsion in number fields
The number fields $K$ of degree less than 24 such that $E(K)_{\rm tors}$ is strictly larger than $E(\Q)_{\rm tors}$ (which is trivial) are as follows:

An entry - indicates that the invariants are not computed because the reduction is additive.
$p$-adic regulators
All $p$-adic regulators are identically $1$ since the rank is $0$.
