InjectivePrefix

Equal decoded values below l have equal indices.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

This node is conservative notation, not a theorem, axiom, predicate constant, or kernel rule. Its expansion remains in the unchanged first-order language.

Grand-campaign planning vocabulary

Locate InjectivePrefix in the global campaign vocabulary →

Reviewed InjectivePrefix corresponds to blueprint InjectivePrefix with checked argument positions [0, 1, 2].

The global atlas describes planning vocabulary and does not itself certify a definition or theorem. The reviewed expansion and conservative dependency DAG on this page are the actual family-local reading definitions.
