---|---|---|---|---|---|---|---|
$2$ | $4$ | $I_{13}^{*}$ | Additive | -1 | 6 | 23 | 5 |
$3$ | $2$ | $I_{6}^{*}$ | Additive | -1 | 2 | 12 | 6 |

$23$ | $6$ | $I_{6}$ | Split multiplicative | -1 | 1 | 6 | 6 |
Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$ except those listed in the table below.
prime $\ell$ | mod-$\ell$ image | $\ell$-adic image |
---|---|---|
$2$ | 2B | 8.6.0.6 |
$3$ | 3B | 3.4.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 552 = 2^{3} \cdot 3 \cdot 23 \), index $96$, genus $1$, and generators
