Claim. Write for the length of the longest interval with for every , the quantity of Problem 452. The report states that
proved by a Richert-type weighted sieve: the weight runs over the primes of a window and is tuned so that its total over an interval of length is positive, which forces a point of the interval where falls below $\log\log n$. Patrick White published the report on 2026-07-26 on erdosproblemaday.com, a public ledger of AI-assisted reports on the catalog's problems that names its authors as Patrick White and Claude (Anthropic); the ledger lists this entry as LIVE with a full write-up and no claimed proof, and gives it no outcome label. The entry credits the bound to GPT-5.6 Sol and links that model's transcript for the argument. It restates the lower bound from the Chinese remainder theorem and calls the gap between the two bounds open.
Covers. The upper bound only. With the lower bound of the site's commentary the size of stays undetermined, and the bound says nothing about whether intervals of length exist for every .
Depends on. Nothing in this wiki.
Standing. Claimed. The report is not refereed, is not filed on the
site's proof-claims tab, and names no reviewer, so it stays claimed; the
site labels the problem OPEN (page last edited 28 October 2025). A

proves for every
independently, by a Brun sieve, and cites the report; a
thread post of 4 July 2026
gives the weaker bound by comparing
three moments of the count of small prime factors, and reports that Erdős
and Graham knew no upper bound. Neither post is a dated manuscript, so
neither has a page.
