Jacobians and polarizations

This isogeny class is principally polarizable and contains the Jacobians of 216 curves (of which all are hyperelliptic):

Decomposition and endomorphism algebra

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

Endomorphism algebra over $\F_{59}$
The isogeny class factors as 1.59.am $\times$ 1.59.ae and its endomorphism algebra is a direct product of the endomorphism algebras for each isotypic factor. The endomorphism algebra for each factor is:
