prime_field_inverse_table_exists

Alpha v34 independently verified · alpha_closed; checked-use authorized; not Stable

Construct every entry of the finite inverse table from primality alone.

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

Constructive proof overview

Generated structural guide

Construct every entry of the finite inverse table from primality alone.

The unchanged tactic script uses 2 declared prerequisites and contains 12 exact native proof lines.

Formal native tactic body

Dependencies are introduced as named hypotheses before line 1. Local theorem links identify exact declared prerequisites. This exact body belongs to a complete independently kernel-checked constructive proof bundle and has Alpha checked-use authority; it does not imply Stable membership.
