- Three verified arXiv papers and one archived software release are directly relevant to formalising Busy Beaver deciders in Lean 4. The literature establishes a Coq proof of S(5) = 47,176,870 and S(2,4) = 3,932,964, documents additional Turing-machine decider techniques, and demonstrates existing Lean 4 formalisation of smaller Busy Beaver proof challenges; it does not establish that the complete Coq-BB5 development has already been ported to Lean 4.
