Local data
This elliptic curve is not semistable. There are 4 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $v_p(N)$ | $v_p(\Delta)$ | $v_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $1$ | $I_0^{*}$ | additive | -1 | 5 | 9 | 0 |
| $5$ | $1$ | $I_{9}$ | nonsplit multiplicative | 1 | 1 | 9 | 9 |
| $11$ | $2$ | $III^{*}$ | additive | 1 | 2 | 9 | 0 |
| $23$ | $4$ | $I_{4}$ | split multiplicative | -1 | 1 | 4 | 4 |
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 \( 440 = 2^{3} \cdot 5 \cdot 11 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 439 & 2 \\ 438 & 3 \end{array}\right),\left(\begin{array}{rr} 221 & 2 \\ 221 & 3 \end{array}\right),\left(\begin{array}{rr} 321 & 2 \\ 321 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 439 & 0 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 111 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 177 & 2 \\ 177 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[440])$ is a degree-$4866048000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/440\Z)$.
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 |
|---|---|---|---|
| $2$ | additive | $4$ | \( 55 = 5 \cdot 11 \) |
| $3$ | good | $2$ | \( 89056 = 2^{5} \cdot 11^{2} \cdot 23 \) |
| $5$ | nonsplit multiplicative | $6$ | \( 89056 = 2^{5} \cdot 11^{2} \cdot 23 \) |
| $11$ | additive | $42$ | \( 3680 = 2^{5} \cdot 5 \cdot 23 \) |
| $23$ | split multiplicative | $24$ | \( 19360 = 2^{5} \cdot 5 \cdot 11^{2} \) |
