Local data
This elliptic curve is semistable. There is only one prime of bad reduction:
prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$505763$ | $1$ | $I_{1}$ | 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 \( 1011526 = 2 \cdot 505763 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 505765 & 2 \\ 505765 & 3 \end{array}\right),\left(\begin{array}{rr} 1011525 & 2 \\ 1011524 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 1011525 & 0 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right)$.
The torsion field $K:=\Q(E[1011526])$ is a degree-$196294718362477838244624$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/1011526\Z)$.
Isogenies
This curve has no rational isogenies. Its isogeny class 505763.a consists of this curve only.
Twists
This elliptic curve is its own minimal quadratic twist.
Iwasawa invariants
No Iwasawa invariant data is available for this curve.
$p$-adic regulators
All $p$-adic regulators are identically $1$ since the rank is $0$.
