Decomposition and endomorphism algebra

Endomorphism algebra over $\F_{5}$
The isogeny class factors as 1.5.ae 2 $\times$ 2.5.ad_e 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 $\overline{\F}_{5}$
The base change of $A$ to $\F_{5^{3}}$ is 1.125.as 2 $\times$ 1.125.ae 2 . The endomorphism algebra for each factor is:
All geometric endomorphisms are defined over $\F_{5^{3}}$.

Base change

This is a primitive isogeny class.
