Local data
This elliptic curve is not semistable. There are 4 primes of bad reduction:
prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $2$ | $I_{8}^{*}$ | Additive | 1 | 6 | 18 | 0 |
$3$ | $3$ | $IV^{*}$ | Additive | -1 | 4 | 10 | 0 |
$5$ | $7$ | $I_{7}$ | Split multiplicative | -1 | 1 | 7 | 7 |
$7$ | $1$ | $I_0^{*}$ | Additive | -1 | 2 | 6 | 0 |
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 |
---|---|---|
$7$ | 7B | 7.8.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 2520 = 2^{3} \cdot 3^{2} \cdot 5 \cdot 7 \), index $96$, genus $2$, and generators
$\left(\begin{array}{rr} 2507 & 14 \\ 2506 & 15 \end{array}\right),\left(\begin{array}{rr} 8 & 5 \\ 91 & 57 \end{array}\right),\left(\begin{array}{rr} 1887 & 1432 \\ 1274 & 1567 \end{array}\right),\left(\begin{array}{rr} 1273 & 2506 \\ 1274 & 2505 \end{array}\right),\left(\begin{array}{rr} 1 & 14 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1763 & 2506 \\ 2261 & 2421 \end{array}\right),\left(\begin{array}{rr} 1259 & 0 \\ 0 & 2519 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 14 & 1 \end{array}\right),\left(\begin{array}{rr} 2511 & 2510 \\ 1442 & 2411 \end{array}\right),\left(\begin{array}{rr} 631 & 14 \\ 637 & 99 \end{array}\right)$.
The torsion field $K:=\Q(E[2520])$ is a degree-$60197437440$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/2520\Z)$.
