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$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $2$ | $I_{10}^{*}$ | Additive | -1 | 4 | 18 | 6 |
$5$ | $4$ | $I_{4}$ | Split multiplicative | -1 | 1 | 4 | 4 |
$7$ | $4$ | $I_{6}^{*}$ | Additive | -1 | 2 | 12 | 6 |
$11$ | $4$ | $I_{1}^{*}$ | Additive | -1 | 2 | 7 | 1 |
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 \( 924 = 2^{2} \cdot 3 \cdot 7 \cdot 11 \), index $96$, genus $1$, and generators
$\left(\begin{array}{rr} 11 & 2 \\ 874 & 915 \end{array}\right),\left(\begin{array}{rr} 662 & 921 \\ 615 & 8 \end{array}\right),\left(\begin{array}{rr} 913 & 12 \\ 912 & 13 \end{array}\right),\left(\begin{array}{rr} 317 & 2 \\ 366 & 13 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 12 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 6 \\ 6 & 37 \end{array}\right),\left(\begin{array}{rr} 1 & 12 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 263 & 912 \\ 654 & 851 \end{array}\right),\left(\begin{array}{rr} 846 & 527 \\ 847 & 538 \end{array}\right)$.
The torsion field $K:=\Q(E[924])$ is a degree-$1277337600$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/924\Z)$.
