How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced — the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted — a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated — a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
A finite -group has order for a prime and some
Definition
Let be a prime natural number (Prime and composite integers: is prime when and its only positive divisors are and ). A finite -group is a finite group (Group and abelian group, The cardinality of a finite set) whose order has the form
for some , with natural exponentiation as in Exponentiation of natural numbers, , and its agreement with the integer power in . The case permits the trivial group. A finite -group is nontrivial exactly when .
