Decomposition of the Jacobian
Splits over the number field \(\Q (b)\) with defining polynomial:
\(x^{6} - x^{5} - 305 x^{4} - 3190 x^{3} - 13345 x^{2} - 24521 x - 15791\)
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
\(g_4 = -\frac{8658775}{12288} b^{5} + \frac{3452205}{2048} b^{4} + \frac{870793155}{4096} b^{3} + \frac{23982982945}{12288} b^{2} + \frac{41041673755}{6144} b + \frac{32513544835}{4096}\)
\(g_6 = -\frac{5246678395}{36864} b^{5} + \frac{50475704531}{147456} b^{4} + \frac{2110058027021}{49152} b^{3} + \frac{907064455213}{2304} b^{2} + \frac{66151883495221}{49152} b + \frac{235489792062851}{147456}\)

Endomorphisms of the Jacobian
Of \(\GL_2\)-type over \(\Q\)
Endomorphism algebra over \(\Q\):
\(\End (J_{}) \otimes \Q \) | \(\simeq\) | \(\Q(\sqrt{-3}) \) |
\(\End (J_{}) \otimes \R\) | \(\simeq\) | \(\C\) |
Smallest field over which all endomorphisms are defined:
Galois number field \(K = \Q (a)\) with defining polynomial \(x^{6} - x^{5} - 305 x^{4} - 3190 x^{3} - 13345 x^{2} - 24521 x - 15791\)
Endomorphism algebra over \(\overline{\Q}\):
\(\End (J_{\overline{\Q}}) \otimes \Q \) | \(\simeq\) | \(\mathrm{M}_2(\)\(\Q\)\()\) |
\(\End (J_{\overline{\Q}}) \otimes \R\) | \(\simeq\) | \(\mathrm{M}_2 (\R)\) |
