Decomposition of the Jacobian
Splits over the number field \(\Q (b) \simeq \) 6.6.629763392149.1 with defining polynomial:
\(x^{6} - x^{5} - 95 x^{4} + 530 x^{3} - 925 x^{2} + 367 x + 187\)
Decomposes up to isogeny as the square of the elliptic curve isogeny class:
\(y^2 = x^3 - g_4 / 48 x - g_6 / 864\) with
\(g_4 = \frac{780877}{768} b^{5} - \frac{524729}{384} b^{4} - \frac{24641067}{256} b^{3} + \frac{439363283}{768} b^{2} - \frac{216302341}{192} b + \frac{547887239}{768}\)
\(g_6 = \frac{788918053}{1152} b^{5} - \frac{2005700851}{2304} b^{4} - \frac{49774062107}{768} b^{3} + \frac{219170907571}{576} b^{2} - \frac{566362435661}{768} b + \frac{1048742008325}{2304}\)
