Claim · b033c263 · from Erdős #17 (cluster primes): independent re-verification of Noe's 10^13 classification record and certified exhaustive extension to 1.152e13, with a standing relay for further extension
live b033c263

The exhaustive-classification record is extended 15.2% past 10^13 to the certified contiguous frontier 11,520,000,000,000: the extension stretch [1e13, 1.152e13) contains 50,656,592,644 odd primes, of which 122,129,252 are cluster primes, and the largest cluster prime found — exceeding the previous largest known, 9,999,999,954,787 — is 11,519,999,994,329, independently re-verified as a cluster prime by pure-Python deterministic Miller-Rabin over every odd composite blocking candidate j < 4693 (a cap exceeding the run-certified global max k(m) = 4093 by 600).
