Local data
This elliptic curve is not semistable. There are 3 primes of bad reduction:

---|---|---|---|---|---|---|---|
$2$ | $2$ | $I_{13}^{*}$ | Additive | 1 | 6 | 23 | 5 |
$5$ | $2$ | $III^{*}$ | Additive | -1 | 2 | 9 | 0 |
$11$ | $1$ | $I_{5}$ | Non-split multiplicative | 1 | 1 | 5 | 5 |
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 |
---|---|---|
$5$ | 5Cs.4.1 | 5.60.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 2200 = 2^{3} \cdot 5^{2} \cdot 11 \), index $1200$, genus $37$, and generators
