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 | $\mathrm{ord}_p(N)$ | $\mathrm{ord}_p(\Delta)$ | $\mathrm{ord}_p(\mathrm{den}(j))$ |
---|---|---|---|---|---|---|---|
$2$ | $1$ | $II$ | additive | 1 | 6 | 6 | 0 |
$3$ | $3$ | $IV^{*}$ | additive | 1 | 4 | 10 | 0 |
$5$ | $1$ | $I_0^{*}$ | additive | 1 | 2 | 6 | 0 |
$7$ | $2$ | $I_0^{*}$ | additive | -1 | 2 | 6 | 0 |
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 |
---|---|---|
$2$ | 2G | 4.2.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 420 = 2^{2} \cdot 3 \cdot 5 \cdot 7 \), index $4$, genus $0$, and generators
$\left(\begin{array}{rr} 1 & 2 \\ 2 & 5 \end{array}\right),\left(\begin{array}{rr} 139 & 0 \\ 0 & 419 \end{array}\right),\left(\begin{array}{rr} 419 & 315 \\ 210 & 419 \end{array}\right),\left(\begin{array}{rr} 1 & 4 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 2 & 3 \\ 415 & 413 \end{array}\right),\left(\begin{array}{rr} 83 & 0 \\ 0 & 419 \end{array}\right),\left(\begin{array}{rr} 179 & 0 \\ 0 & 419 \end{array}\right),\left(\begin{array}{rr} 417 & 4 \\ 416 & 5 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 4 & 1 \end{array}\right),\left(\begin{array}{rr} 419 & 0 \\ 210 & 419 \end{array}\right)$.
The torsion field $K:=\Q(E[420])$ is a degree-$1114767360$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/420\Z)$.
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 | $2$ | \( 99225 = 3^{4} \cdot 5^{2} \cdot 7^{2} \) |
$3$ | additive | $4$ | \( 1120 = 2^{5} \cdot 5 \cdot 7 \) |
$5$ | additive | $14$ | \( 254016 = 2^{6} \cdot 3^{4} \cdot 7^{2} \) |
$7$ | additive | $26$ | \( 129600 = 2^{6} \cdot 3^{4} \cdot 5^{2} \) |
