Busy Beaver BB(5) = 47,176,870 Proven After 40-Year Search — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: FINDING: BB(5) = 47,176,870 proven after 40-year search via distributed "Busy Beaver Challenge" collaboration — the 5-state Busy Beaver champion halts after 47,176,870 steps, establishing the exact value of the 5th Busy Beaver number | MATH: BB(5) = 47,176,870; BB(n) = max{steps(M) | M halts, M has n states, blank tape}; Σ(5) = 4098 (max 1s written); growth rate: BB(n) > f_ω(n) in fast-growing hierarchy, dominates all computable functions | CONNECTION: None — Busy Beaver values are combinatorial/computational extremes with no known algebraic structure linking to φ, √φ, base-60, or crystallographic root systems; the function's non-computability places it outside geometric harmony frameworks | DEPTH: 8 Author: Andrew Stewart Caldin, Independent Researcher, UK.
