## 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
3 3.3.2296.1 $$\Z/2\Z$$ Not in database
6 $$\Q(\zeta_{7})$$ $$\Z/7\Z$$ Not in database
6.6.12103630336.1 $$\Z/2\Z \times \Z/2\Z$$ Not in database
7 7.1.6200896666048.2 $$\Z/7\Z$$ 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.
