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.

FALSE: every transitive action is primitive

Statement

Every transitive action is primitive.

Facts & Assumptions

Given: The regular action of Cn on itself for a composite integer n.

[L1]

In the regular cyclic action, the blocks are exactly the cosets of subgroups. For composite n this yields nontrivial blocks (Blocks in a regular cyclic action are cosets of subgroups).

Refutation

technique · direct
1.1givenalgebra

The regular action of Cn on itself is transitive, since every point is reached by a translation.

1.2L1

When n is composite, [L1] gives a nontrivial block system coming from a proper nontrivial subgroup of Cn. So this transitive action is not primitive.

Steps 1.1 and 1.2 refute the statement.

Dependency tree · two levels

3 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.
