specific-question The question Alternate descriptions of finite fields has the deprecated (abstract-algebra) tag and it also has no top-level tag. As I am not really sure which top-level tag would be suitable for questions concerning finite fields, I should probably leave reatagging to some other user.

The finite field of order $p^n$ is isomorphic to $(\mathbb Z/p \mathbb Z)[X]/(P)$, where $P$ is an irreducible polynomial in $(\mathbb Z/p \mathbb Z)[X]$ of degree $n$. This describes every finite field up to isomorphism. My question is, what are alternate ways of describing these finite fields?...

specific-question This recent question also has a deprecated tag: Combinatorial property of cross polytopes. But I'm not really sure what to replace (geometry) with. Perhaps mg.metric-geometry? Maybe also convex-polytopes and polytopes (or at least the first one) could be added?

Maybe I will remind the decomposition-theorem tag again. Todd Trimble (one of the moderators) explicitly said that the tag should be removed: chat.stackexchange.com/transcript/10243/2018/4/26 - but it still seems to be there.
