$2$ | $2$ | $I_{17}^{*}$ | Additive | 1 | 6 | 27 | 9 |
$3$ | $2$ | $I_{6}$ | Non-split multiplicative | 1 | 1 | 6 | 6 |
$19$ | $6$ | $I_{6}$ | Split multiplicative | -1 | 1 | 6 | 6 |
$113$ | $2$ | $I_{2}$ | Split multiplicative | -1 | 1 | 2 | 2 |
Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$ except those listed in the table below.
