Local data
This elliptic curve is not semistable. There are 4 primes of bad reduction:

$2$ | $1$ | $I_{15}$ | Non-split multiplicative | 1 | 1 | 15 | 15 |
$3$ | $2$ | $I_{10}$ | Non-split multiplicative | 1 | 1 | 10 | 10 |
$5$ | $3$ | $IV^{*}$ | Additive | -1 | 2 | 8 | 0 |
$31$ | $1$ | $I_{1}$ | Split multiplicative | -1 | 1 | 1 | 1 |
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 |
---|---|---|
$5$ | 5B.1.4 | 5.24.0.2 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 1240 = 2^{3} \cdot 5 \cdot 31 \), index $48$, genus $1$, and generators
$\left(\begin{array}{rr} 311 & 10 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 621 & 10 \\ 625 & 51 \end{array}\right),\left(\begin{array}{rr} 1231 & 10 \\ 1230 & 11 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 10 & 1 \end{array}\right),\left(\begin{array}{rr} 929 & 610 \\ 0 & 433 \end{array}\right),\left(\begin{array}{rr} 561 & 10 \\ 325 & 51 \end{array}\right),\left(\begin{array}{rr} 6 & 13 \\ 1185 & 1121 \end{array}\right),\left(\begin{array}{rr} 1 & 10 \\ 0 & 1 \end{array}\right)$.
