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$(j)_{-}$ |
---|---|---|---|---|---|---|---|
$2$ | $2$ | $I_{4}^{*}$ | Additive | 1 | 6 | 14 | 0 |
$7$ | $1$ | $II^{*}$ | Additive | -1 | 2 | 10 | 0 |
$17$ | $1$ | $I_{1}$ | 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 label 68.2.0.a.1, level \( 68 = 2^{2} \cdot 17 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 35 & 2 \\ 35 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 67 & 0 \end{array}\right),\left(\begin{array}{rr} 67 & 2 \\ 66 & 3 \end{array}\right),\left(\begin{array}{rr} 37 & 2 \\ 37 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[68])$ is a degree-$3760128$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/68\Z)$.
Isogenies
This curve has no rational isogenies. Its isogeny class 53312bg consists of this curve only.
Twists
The minimal quadratic twist of this elliptic curve is 3332c1, its twist by $-56$.
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 |
---|---|---|---|
$3$ | 3.1.3332.1 | \(\Z/2\Z\) | Not in database |
$6$ | 6.0.754951232.1 | \(\Z/2\Z \oplus \Z/2\Z\) | 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.

$p$ | 2 | 3 | 5 | 7 | 11 | 13 | 17 | 19 | 23 | 29 | 31 | 37 | 41 | 43 | 47 |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Reduction type | add | ss | ord | add | ord | ord | split | ord | ord | ss | ord | ord | ss | ord | ord |
$\lambda$-invariant(s) | - | 1,1 | 3 | - | 1 | 1 | 2 | 1 | 1 | 1,1 | 1 | 1 | 1,1 | 1 | 1 |
$\mu$-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
Note: $p$-adic regulator data only exists for primes $p\ge 5$ of good ordinary reduction.
