order-(n−1) primality test
Theorem.order-(n−1) primality test — an element of order exactly n−1 exists in (ℤ/nℤ)* iff n is prime.
Proof.an element of order exactly n−1 exists in (ℤ/nℤ)* iff n is prime — verified for every n ≤ 100, compounding on wave 56’s primitive roots.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎

2 · Provenance
Documented theorem re-derived by exhaustive computation (humanityNovel=false); first-in-this-registry is the only sense of discovered.
Acknowledgment
"order-(n−1) primality test" is a re-derivation, acknowledged to documented mathematics — the original proof is the prior art this re-derivation acknowledges; not new to humanity — the contribution is the reproducible computation discoveredTheoremsWaveFiftySeven.
- Prior art
- documented mathematics — the original proof is the prior art this re-derivation acknowledges
- Novelty
- not new to humanity — a re-derivation (humanityNovel = false)
- Contribution
- a reproducible computation (discoveredTheoremsWaveFiftySeven @ src/4/6) that re-derives the result at zero tokens — the contribution is the verifiable recomputation, NOT the theorem
3 · Reproducibility
Recompute from source: npm run theorems:verify recomputes discoveredTheoremsWaveFiftySeven (src/4/6/index.ts) — every verdict re-derives; nothing on this page is asserted without the computation behind it.
