Local data
This elliptic curve is not semistable. There are 5 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $v_p(N)$ | $v_p(\Delta)$ | $v_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $1$ | $I_{1}$ | nonsplit multiplicative | 1 | 1 | 1 | 1 |
| $3$ | $6$ | $I_{6}$ | split multiplicative | -1 | 1 | 6 | 6 |
| $11$ | $8$ | $I_{8}$ | split multiplicative | -1 | 1 | 8 | 8 |
| $17$ | $3$ | $IV^{*}$ | additive | -1 | 2 | 8 | 0 |
| $23$ | $1$ | $I_{1}$ | split multiplicative | -1 | 1 | 1 | 1 |
Galois representations
The $\ell$-adic Galois representation has maximal image for all primes $\ell$.
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 184 = 2^{3} \cdot 23 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 93 & 2 \\ 93 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 97 & 2 \\ 97 & 3 \end{array}\right),\left(\begin{array}{rr} 183 & 2 \\ 182 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 47 & 2 \\ 47 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 183 & 0 \end{array}\right)$.
The torsion field $K:=\Q(E[184])$ is a degree-$205185024$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/184\Z)$.
The table below list all primes $\ell$ for which the Serre invariants associated to the mod-$\ell$ Galois representation are exceptional.
| $\ell$ | Reduction type | Serre weight | Serre conductor |
|---|---|---|---|
| $2$ | nonsplit multiplicative | $4$ | \( 6647 = 17^{2} \cdot 23 \) |
| $3$ | split multiplicative | $4$ | \( 146234 = 2 \cdot 11 \cdot 17^{2} \cdot 23 \) |
| $11$ | split multiplicative | $12$ | \( 39882 = 2 \cdot 3 \cdot 17^{2} \cdot 23 \) |
| $17$ | additive | $114$ | \( 1518 = 2 \cdot 3 \cdot 11 \cdot 23 \) |
| $23$ | split multiplicative | $24$ | \( 19074 = 2 \cdot 3 \cdot 11 \cdot 17^{2} \) |
