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.

No group of order pq for distinct primes is simple

Statement

No group of order pq for distinct primes is simple. See If p<q are primes and ∣G∣=pq, then G has a normal subgroup of order q.

Facts & Assumptions

Given: The hypotheses and objects in the Statement.

[L1]

Let p<q be primes. Every group G of order pq has a normal subgroup of order q. (If p<q are primes and ∣G∣=pq, then G has a normal subgroup of order q).

[L2]

A group G is simple if G≠{1} and its only normal subgroups are {1} and G, where normality is as in def-normal-subgroup. (Simple groups).

Proof

technique · direct
1.1L1L2givenalgebra

We order the primes as p<q.

2.1step 1.1givenalgebra∎

The published order-pq lemma supplies a normal subgroup of order q, which is nontrivial and proper. This proves the stated claim.

Dependency tree · two levels

14 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
