Local data at primes of bad reduction
This elliptic curve is not semistable. There are 4 primes $p$ of bad reduction:
| $p$ | Tamagawa number | Kodaira symbol | Reduction type | Root number | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
|---|---|---|---|---|---|---|---|
| $2$ | $1$ | $I_{5}$ | nonsplit multiplicative | 1 | 1 | 5 | 5 |
| $3$ | $1$ | $I_{1}$ | nonsplit multiplicative | 1 | 1 | 1 | 1 |
| $41$ | $1$ | $I_{1}$ | 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 \( 984 = 2^{3} \cdot 3 \cdot 41 \), index $2$, genus $0$, and generators
$\left(\begin{array}{rr} 247 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 2 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 2 & 1 \end{array}\right),\left(\begin{array}{rr} 493 & 2 \\ 493 & 3 \end{array}\right),\left(\begin{array}{rr} 457 & 2 \\ 457 & 3 \end{array}\right),\left(\begin{array}{rr} 1 & 1 \\ 983 & 0 \end{array}\right),\left(\begin{array}{rr} 983 & 2 \\ 982 & 3 \end{array}\right),\left(\begin{array}{rr} 329 & 2 \\ 329 & 3 \end{array}\right)$.
The torsion field $K:=\Q(E[984])$ is a degree-$101567692800$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/984\Z)$.
The table below list all primes $\ell$ for which the Serre invariants associated to the mod-$\ell$ Galois representation are exceptional.

|---|---|---|---|
| $2$ | nonsplit multiplicative | $4$ | \( 227427 = 3 \cdot 41 \cdot 43^{2} \) |
| $3$ | nonsplit multiplicative | $4$ | \( 151618 = 2 \cdot 41 \cdot 43^{2} \) |
| $5$ | good | $2$ | \( 227427 = 3 \cdot 41 \cdot 43^{2} \) |
| $41$ | split multiplicative | $42$ | \( 11094 = 2 \cdot 3 \cdot 43^{2} \) |
