Local data
This elliptic curve is not semistable. There are 3 primes of bad reduction:
prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$3$ | $2$ | $III$ | Additive | 1 | 2 | 3 | 0 |
$13$ | $1$ | $I_0^{*}$ | Additive | 1 | 2 | 6 | 0 |
$17$ | $1$ | $II$ | Additive | 1 | 2 | 2 | 0 |
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 label 6.6.0.b.1, level \( 6 = 2 \cdot 3 \), index $6$, genus $0$, and generators
$\left(\begin{array}{rr} 0 & 5 \\ 1 & 5 \end{array}\right),\left(\begin{array}{rr} 3 & 2 \\ 5 & 5 \end{array}\right)$.
The torsion field $K:=\Q(E[6])$ is a degree-$48$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/6\Z)$.
