Local data
This elliptic curve is not semistable. There are 5 primes of bad reduction:
prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $13$ | $I_{13}$ | Split multiplicative | -1 | 1 | 13 | 13 |
$3$ | $4$ | $I_{1}^{*}$ | Additive | -1 | 2 | 7 | 1 |
$5$ | $1$ | $II$ | Additive | 1 | 2 | 2 | 0 |
$7$ | $2$ | $I_{1}^{*}$ | Additive | -1 | 2 | 7 | 1 |
$19$ | $3$ | $I_{3}$ | Split multiplicative | -1 | 1 | 3 | 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 \( 3192 = 2^{3} \cdot 3 \cdot 7 \cdot 19 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 799 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 3191 & 2 \\ 3190 & 3 \end{array}\right),\left(\begin{array}{rr} 2129 & 2 \\ 2129 & 3 \end{array}\right),\left(\begin{array}{rr} 1009 & 2 \\ 1009 & 3 \end{array}\right),\left(\begin{array}{rr} 1597 & 2 \\ 1597 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 3191 & 0 \end{array}\right),\left(\begin{array}{rr} 913 & 2 \\ 913 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[3192])$ is a degree-$9150010490880$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/3192\Z)$.
