BSD formula
$\displaystyle 5.330071938 \approx L(E,1) = \frac{\# Ш(E/\Q)\cdot \Omega_E \cdot \mathrm{Reg}(E/\Q) \cdot \prod_p c_p}{\#E(\Q)_{\rm tor}^2} \approx \frac{36 \cdot 0.018507 \cdot 1.000000 \cdot 32}{2^2} \approx 5.330071938$

Local data
This elliptic curve is not semistable. There are 4 primes of bad reduction:
| prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $I_{10}^{*}$ | Additive | -1 | 6 | 20 | 2 |
| $3$ | $4$ | $I_{1}^{*}$ | Additive | -1 | 2 | 7 | 1 |
| $5$ | $2$ | $I_{1}^{*}$ | Additive | 1 | 2 | 7 | 1 |
| $31$ | $2$ | $I_{2}$ | Split multiplicative | -1 | 1 | 2 | 2 |
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 |
|---|---|---|
| $2$ | 2B | 16.48.0.188 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 7440 = 2^{4} \cdot 3 \cdot 5 \cdot 31 \), index $192$, genus $1$, and generators
$\left(\begin{array}{rr} 7425 & 16 \\ 7424 & 17 \end{array}\right),\left(\begin{array}{rr} 15 & 2 \\ 7342 & 7427 \end{array}\right),\left(\begin{array}{rr} 1 & 16 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 5 & 4 \\ 7436 & 7437 \end{array}\right),\left(\begin{array}{rr} 4448 & 7435 \\ 45 & 14 \end{array}\right),\left(\begin{array}{rr} 2464 & 7435 \\ 45 & 14 \end{array}\right),\left(\begin{array}{rr} 922 & 5575 \\ 6507 & 3718 \end{array}\right),\left(\begin{array}{rr} 1 & 0 \\ 16 & 1 \end{array}\right),\left(\begin{array}{rr} 4813 & 16 \\ 224 & 7125 \end{array}\right),\left(\begin{array}{rr} 7427 & 7424 \\ 5836 & 5895 \end{array}\right)$.
The torsion field $K:=\Q(E[7440])$ is a degree-$2632974336000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/7440\Z)$.
