BSD formula
$\displaystyle 1.763901810 \approx L(E,1) = \frac{\# Ш(E/\Q)\cdot \Omega_E \cdot \mathrm{Reg}(E/\Q) \cdot \prod_p c_p}{\#E(\Q)_{\rm tor}^2} \approx \frac{1 \cdot 0.110244 \cdot 1.000000 \cdot 64}{2^2} \approx 1.763901810$

| prime | Tamagawa number | Kodaira symbol | Reduction type | Root number | ord($N$) | ord($\Delta$) | ord$(j)_{-}$ |
|---|---|---|---|---|---|---|---|
| $2$ | $2$ | $I_{11}^{*}$ | Additive | 1 | 6 | 21 | 3 |
| $3$ | $2$ | $I_{1}^{*}$ | Additive | -1 | 2 | 7 | 1 |
| $5$ | $1$ | $I_{1}$ | Non-split multiplicative | 1 | 1 | 1 | 1 |
| $11$ | $4$ | $I_{4}$ | Split multiplicative | -1 | 1 | 4 | 4 |

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 | 4.6.0.1 |
The image $H:=\rho_E(\Gal(\overline{\Q}/\Q))$ of the adelic Galois representation has level \( 17160 = 2^{3} \cdot 3 \cdot 5 \cdot 11 \cdot 13 \), index $48$, genus $0$, and generators
$\left(\begin{array}{rr} 1 & 0 \\ 8 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 8 \\ 0 & 1 \end{array}\right),\left(\begin{array}{rr} 1 & 4 \\ 4 & 17 \end{array}\right),\left(\begin{array}{rr} 13736 & 3 \\ 5 & 2 \end{array}\right),\left(\begin{array}{rr} 11432 & 17157 \\ 11435 & 17158 \end{array}\right),\left(\begin{array}{rr} 7801 & 8 \\ 14044 & 33 \end{array}\right),\left(\begin{array}{rr} 6443 & 6436 \\ 6482 & 15021 \end{array}\right),\left(\begin{array}{rr} 6432 & 15007 \\ 10733 & 10746 \end{array}\right),\left(\begin{array}{rr} 2641 & 8 \\ 10564 & 33 \end{array}\right),\left(\begin{array}{rr} 7 & 6 \\ 17154 & 17155 \end{array}\right),\left(\begin{array}{rr} 17153 & 8 \\ 17152 & 9 \end{array}\right)$.
The torsion field $K:=\Q(E[17160])$ is a degree-$255058771968000$ Galois extension of $\Q$ with $\Gal(K/\Q)$ isomorphic to the projection of $H$ to $\GL_2(\Z/17160\Z)$.
