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$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $2$ | $I_{2}^{*}$ | Additive | -1 | 6 | 12 | 0 |
$3$ | $2$ | $I_{4}^{*}$ | Additive | -1 | 2 | 10 | 4 |
$5$ | $2$ | $III^{*}$ | Additive | -1 | 2 | 9 | 0 |
$7$ | $2$ | $I_0^{*}$ | 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 |
---|---|---|
$2$ | 2B | 8.24.0.135 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 1680 = 2^{4} \cdot 3 \cdot 5 \cdot 7 \), index $192$, genus $3$, and generators
$\left(\begin{array}{rr} 7 & 16 \\ 248 & 567 \end{array}\right),\left(\begin{array}{rr} 664 & 945 \\ 511 & 1168 \end{array}\right),\left(\begin{array}{rr} 1 & 16 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1665 & 16 \\ 1664 & 17 \end{array}\right),\left(\begin{array}{rr} 15 & 76 \\ 1004 & 1615 \end{array}\right),\left(\begin{array}{rr} 1439 & 0 \\ 0 & 1679 \end{array}\right),\left(\begin{array}{rr} 237 & 224 \\ 728 & 1189 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 16 & 1 \end{array}\right),\left(\begin{array}{rr} 195 & 1484 \\ 1456 & 181 \end{array}\right),\left(\begin{array}{rr} 7 & 4 \\ 68 & 39 \end{array}\right),\left(\begin{array}{rr} 1259 & 70 \\ 714 & 419 \end{array}\right)$.
The torsion field $K:=\Q(E[1680])$ is a degree-$5945425920$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/1680\Z)$.
