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$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $4$ | $I_{12}^{*}$ | Additive | -1 | 4 | 20 | 8 |
$3$ | $1$ | $I_{1}$ | Non-split multiplicative | 1 | 1 | 1 | 1 |
$5$ | $4$ | $I_{9}^{*}$ | Additive | 1 | 2 | 15 | 9 |
$19$ | $4$ | $I_{6}^{*}$ | Additive | -1 | 2 | 12 | 6 |
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 | 2.3.0.1 |
$3$ | 3B | 3.4.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 1140 = 2^{2} \cdot 3 \cdot 5 \cdot 19 \), index $96$, genus $1$, and generators
$\left(\begin{array}{rr} 1041 & 662 \\ 454 & 79 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 12 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 6 \\ 6 & 37 \end{array}\right),\left(\begin{array}{rr} 1130 & 1137 \\ 939 & 8 \end{array}\right),\left(\begin{array}{rr} 11 & 2 \\ 1090 & 1131 \end{array}\right),\left(\begin{array}{rr} 359 & 1128 \\ 1014 & 1067 \end{array}\right),\left(\begin{array}{rr} 1 & 12 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1129 & 12 \\ 1128 & 13 \end{array}\right),\left(\begin{array}{rr} 770 & 3 \\ 733 & 1132 \end{array}\right)$.
The torsion field $K:=\Q(E[1140])$ is a degree-$2836684800$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/1140\Z)$.
