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
$3$ 3.1.1144.1 \(\Z/2\Z\) Not in database
$6$ 6.0.1497193984.1 \(\Z/2\Z \times \Z/2\Z\) Not in database
$8$ 8.2.3465933379972272.8 \(\Z/3\Z\) Not in database
