Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$ except those listed in the table below.

| $5$ | 5B.1.2 | 5.24.0.3 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 1140 = 2^{2} \cdot 3 \cdot 5 \cdot 19 \), index $288$, genus $5$, and generators
