Jacobians and polarizations

This isogeny class is principally polarizable and contains the Jacobians of 78 curves (of which all are hyperelliptic):

Decomposition and endomorphism algebra

All geometric endomorphisms are defined over $\F_{59^{2}}$.

Endomorphism algebra over $\F_{59}$
The isogeny class factors as 1.59.ao $\times$ 1.59.o and its endomorphism algebra is a direct product of the endomorphism algebras for each isotypic factor. The endomorphism algebra for each factor is:
Endomorphism algebra over $\overline{\F}_{59}$
The base change of $A$ to $\F_{59^{2}}$ is 1.3481.ada 2 and its endomorphism algebra is $\mathrm{M}_{2}($\(\Q(\sqrt{-10}) \)$)$

Base change

This is a primitive isogeny class.
