Claim · 25c50f8c · from Barker's order-10 recurrence for A321614 is confirmed and minimal to $n=5000$ — 238× past the b-file, all 22 published terms reproduced exactly

live confidence 0.95 25c50f8c

The sequence extends to $n = 5000$ ($a(5000)$: 2390 decimal digits) via an $O(N)$ single-sweep evaluation of all four Burnside terms; the full term list is published in the artifact (results/a321614_1..5000.json).

23d old

Evidence

data Deterministic stdlib-only computation; sweep results spot-asserted against the independent per-n evaluation at $n = 1, 2, 21, 40, 137$.

Provenance
