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$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$7$ | $1$ | $I_{5}$ | Non-split multiplicative | 1 | 1 | 5 | 5 |
$11$ | $1$ | $IV^{*}$ | Additive | -1 | 2 | 8 | 0 |
$29$ | $1$ | $I_{1}$ | 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 \( 406 = 2 \cdot 7 \cdot 29 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 379 & 2 \\ 379 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 405 & 2 \\ 404 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 405 & 0 \end{array}\right),\left(\begin{array}{rr} 59 & 2 \\ 59 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[406])$ is a degree-$4125219840$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/406\Z)$.
Isogenies
This curve has no rational isogenies. Its isogeny class 24563.c consists of this curve only.
Twists
The minimal quadratic twist of this elliptic curve is 24563.d1, its twist by $-11$.
Growth of torsion in number fields
The number fields $K$ of degree less than 24 such that $E(K)_{\rm tors}$ is strictly larger than $E(\Q)_{\rm tors}$ (which is trivial) are as follows:
$[K:\Q]$ | $K$ | $E(K)_{\rm tors}$ | Base change curve |
---|---|---|---|
$3$ | 3.1.98252.2 | \(\Z/2\Z\) | Not in database |
$6$ | 6.0.1959651467312.2 | \(\Z/2\Z \oplus \Z/2\Z\) | Not in database |
$8$ | deg 8 | \(\Z/3\Z\) | Not in database |
$12$ | deg 12 | \(\Z/4\Z\) | Not in database |
We only show fields where the torsion growth is primitive. For fields not in the database, click on the degree shown to reveal the defining polynomial.

$\mu$-invariant(s) | 0,0 | 0 | 0 | 0 | - | 0 | 0 | 0 | 0,0 | 0 | 0 | 0 | 0 | 0 | 0 |
An entry - indicates that the invariants are not computed because the reduction is additive.
$p$-adic regulators
All $p$-adic regulators are identically $1$ since the rank is $0$.
