Problem 251 Page, Discussion and Proof Claims
bloom_2026_erdos_problem_251_discussion: Identifies the dated public page, discussion comments, proof claim and history for Problem 251, with the commenters' own qualifications.
reformulation_gap_series: Proves Tao's identity that the prime series equals two plus the dyadic series of prime gaps, so the two irrationality questions coincide.
The
source record
identifies the inspected public problem page, its nine discussion comments,
its single registered proof claim and its revision history, all
snapshotted on 2026-09-17 (UTC). This is a web source unit; no canonical
PDF exists for the online material. The only mathematics compiled from it
is Tao's two-line reformulation,
proved in full here.
The other comments announce or discuss manuscripts that have their own
source cards or are recorded as claims with their authors' qualifications;
nothing on the forum is treated as acceptance or review. The capture
discussion_20260917.html.gz (the page titled "251 Discussion Thread | Erdős
Problems", snapshotted 2026-09-17) contains no copyright, license or terms line,
and the site's homepage and FAQ (https://www.erdosproblems.com/ and

Compilation scope. The reformulation is a complete elementary identity, checked here. Everything else in this unit is a dated record of what the site displayed; comments are author claims and confer no mathematical standing.
Bears on. #251.
