Jacobians and polarizations

This isogeny class is principally polarizable and contains the Jacobians of 267 curves (of which all are hyperelliptic):

Decomposition and endomorphism algebra

All geometric endomorphisms are defined over $\F_{73}$.

Endomorphism algebra over $\F_{73}$
The isogeny class factors as 1.73.ao $\times$ 1.73.h and its endomorphism algebra is a direct product of the endomorphism algebras for each isotypic factor. The endomorphism algebra for each factor is:

Base change
