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$(j)_{-}$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $I_{6}$ | Non-split multiplicative | 1 | 1 | 6 | 6 |
| $3$ | $2$ | $III^{*}$ | Additive | 1 | 2 | 9 | 0 |
| $7$ | $1$ | $II^{*}$ | Additive | -1 | 2 | 10 | 0 |
| $11$ | $1$ | $I_{5}$ | Non-split multiplicative | 1 | 1 | 5 | 5 |
Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$.
$p$-adic regulators
All $p$-adic regulators are identically $1$ since the rank is $0$.

An entry - indicates that the invariants are not computed because the reduction is additive.
Isogenies
This curve has no rational isogenies. Its isogeny class 9702.f consists of this curve only.
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 |
|---|---|---|---|
| $3$ | 3.1.6468.1 | \(\Z/2\Z\) | Not in database |
| $6$ | 6.0.5522223168.1 | \(\Z/2\Z \times \Z/2\Z\) | Not in database |
| $8$ | 8.2.3767105332683.2 | \(\Z/3\Z\) | Not in database |
| $12$ | Deg 12 | \(\Z/4\Z\) | Not in database |
