Claim. For every prime , is a sum of three unit fractions. The statement is the authors' report of a completed computation in Further verification and empirical evidence for the Erdős-Straus conjecture (arXiv:2509.00128v1, 29 August 2025), Section 2, recorded on the library's result page: a modular-filter search extending Salez's verification for primes up to , through residue classes modulo and prime filters. The paper allows repeated terms.
Covers. Every with for Problem 242: the primes by the reported computation, the composites through a prime factor, with the terms made distinct as the problem page's Formulation records. Every larger is not covered.
Depends on. No page of this wiki.
Standing. Claimed. The preprint is a computation report without a
journal reference; the computation was not rerun by the corpus and no one
has checked it. The site's commentary cites it for the verification of all
, but the site labels the problem FALSIFIABLE, an open problem,
so the citation is no reviewed evidence.
