An entry - indicates that the invariants are not computed because the reduction is additive.

Isogenies

This curve has non-trivial cyclic isogenies of degree \(d\) for \(d=\) 3.
Its isogeny class 35739.n consists of 2 curves linked by isogenies of degree 3.

Growth of torsion in number fields

The number fields $K$ of degree up to 7 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
2 \(\Q(\sqrt{57}) \) \(\Z/3\Z\) Not in database
3 3.1.44.1 \(\Z/2\Z\) Not in database
6 6.0.21296.1 \(\Z/2\Z \times \Z/2\Z\) Not in database
6.2.358533648.2 \(\Z/6\Z\) Not in database
6.0.22284891.1 \(\Z/3\Z\) Not in database

We only show fields where the torsion growth is primitive. For each field $K$ we either show its label, or a defining polynomial when $K$ is not in the database.
