Local data
This elliptic curve is not semistable. There are 5 primes of bad reduction:
prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $2$ | $I_{2}$ | Non-split multiplicative | 1 | 1 | 2 | 2 |
$3$ | $4$ | $I_{6}^{*}$ | Additive | -1 | 2 | 12 | 6 |
$5$ | $1$ | $I_{1}$ | Non-split multiplicative | 1 | 1 | 1 | 1 |
$11$ | $1$ | $II$ | Additive | -1 | 2 | 2 | 0 |
$37$ | $1$ | $I_{1}$ | Non-split multiplicative | 1 | 1 | 1 | 1 |
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 level \( 740 = 2^{2} \cdot 5 \cdot 37 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 739 & 2 \\ 738 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 739 & 0 \end{array}\right),\left(\begin{array}{rr} 297 & 2 \\ 297 & 3 \end{array}\right),\left(\begin{array}{rr} 261 & 2 \\ 261 & 3 \end{array}\right),\left(\begin{array}{rr} 371 & 2 \\ 371 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[740])$ is a degree-$41982935040$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/740\Z)$.
