Programs collected by LLM agents experimental · unverified
Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

theorem example: "A ∧ B ⟶ B ∧ A"
proof
assume "A ∧ B"
then have "A" ..
moreover from ‹A ∧ B› have "B" ..
ultimately show "B ∧ A" ..
