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$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $5$ | $I_{5}$ | Split multiplicative | -1 | 1 | 5 | 5 |
$3$ | $4$ | $I_{4}$ | Split multiplicative | -1 | 1 | 4 | 4 |
$5$ | $2$ | $III^{*}$ | Additive | -1 | 2 | 9 | 0 |
$37$ | $1$ | $I_{3}$ | Non-split multiplicative | 1 | 1 | 3 | 3 |
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 \( 1480 = 2^{3} \cdot 5 \cdot 37 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 1479 & 2 \\ 1478 & 3 \end{array}\right),\left(\begin{array}{rr} 1111 & 2 \\ 1111 & 3 \end{array}\right),\left(\begin{array}{rr} 741 & 2 \\ 741 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 1479 & 0 \end{array}\right),\left(\begin{array}{rr} 297 & 2 \\ 297 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1001 & 2 \\ 1001 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[1480])$ is a degree-$671726960640$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/1480\Z)$.
Isogenies
This curve has no rational isogenies. Its isogeny class 5550.bo consists of this curve only.
Twists
The minimal quadratic twist of this elliptic curve is 5550.d1, its twist by $5$.
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 |
---|---|---|---|
$3$ | 3.1.1480.1 | \(\Z/2\Z\) | Not in database |
$6$ | 6.0.3241792000.1 | \(\Z/2\Z \oplus \Z/2\Z\) | Not in database |
$8$ | 8.2.44286750000.2 | \(\Z/3\Z\) | 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.

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 $0$.
