One minor (relevant) error with tests/docs/CI. |

Thanks, should be fixed. |

Tiny comment about documentation, otherwise looks good to me. |

…nical ...hence the output here would be more or less meaningless. We should fail instead, until algebraic closures of non-prime finite fields are supported "properly". (reverts part of 87e912b)

Thanks for the review, @S17A05! I think I've addressed all your comments. |
|
Documentation preview for this PR (built with commit a2fdcc9; changes) is ready! 🎉 |
Thanks for the changes, looks good to me now! (For the record: The timeout in the long [p-z] tests is unrelated) |

Currently, the best(?) way to compute embeddings between fields is
somewhat hidden inside the `Hom` object. In this patch we add helper
methods to access such embeddings. In addition, we add an
`.algebraic_closure()` method to non-prime finite fields.
These seem useful.
