Local data at primes of bad reduction
This elliptic curve is not semistable. There are 3 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $I_{2}$ | nonsplit multiplicative | 1 | 1 | 2 | 2 |
| $3$ | $19$ | $I_{19}$ | split multiplicative | -1 | 1 | 19 | 19 |
| $43$ | $2$ | $I_{1}^{*}$ | 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 \( 516 = 2^{2} \cdot 3 \cdot 43 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 515 & 2 \\ 514 & 3 \end{array}\right),\left(\begin{array}{rr} 173 & 2 \\ 173 & 3 \end{array}\right),\left(\begin{array}{rr} 259 & 2 \\ 259 & 3 \end{array}\right),\left(\begin{array}{rr} 433 & 2 \\ 433 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 515 & 0 \end{array}\right)$.
The torsion field $K:=\Q(E[516])$ is a degree-$7689572352$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/516\Z)$.
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 | $4$ | \( 5547 = 3 \cdot 43^{2} \) |
| $3$ | split multiplicative | $4$ | \( 3698 = 2 \cdot 43^{2} \) |
| $19$ | good | $2$ | \( 3698 = 2 \cdot 43^{2} \) |
| $43$ | additive | $968$ | \( 6 = 2 \cdot 3 \) |

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:
| $[K:\Q]$ | $K$ | $E(K)_{\rm tors}$ | Base change curve |
|---|---|---|---|
| $3$ | 3.1.516.1 | \(\Z/2\Z\) | not in database |
| $6$ | 6.0.137388096.1 | \(\Z/2\Z \oplus \Z/2\Z\) | not in database |
| $8$ | deg 8 | \(\Z/3\Z\) | not in database |
| $12$ | deg 12 | \(\Z/4\Z\) | not in database |

An entry - indicates that the invariants are not computed because the reduction is additive.
