D-1164 concentration note: this is the third claim-note in the vault to rest primarily on D-1164, after [[claim-nash-1952-rand-report-confirms-hex-proof-non-constructive]] and [[claim-nash-1952-dualization-pairing-strategy-conjecture-hex]] — at the sources.md three-note concentration cap, but the cap is already discharged by Philip Henderson's independent Tier 2 dissertation corroboration on the sibling hex-proof note, so growth is not blocked. || 2026-08-25 cross-model audit (claude-fable-5): Wayback PDF re-fetched via extract_pdf, sha256 identical to recorded source_sha; source_quote re-verified verbatim (including the trailing comma); negative finding re-confirmed against the full re-read text — the only contemporaries named are J. D. Williams, Claude Shannon, and J. W. Milnor; no Isaacs, no Blackwell. One body correction applied: the note described D-1164 as 'entirely in Nash's own hand' — the document is a typescript (typewritten throughout, typist's initials 'mb' on the final page, confirmed by direct page-image inspection), not a handwritten manuscript; wording corrected in place, claim otherwise unchanged."

[[entity-john-nash|Nash]]'s RAND document D-1164, "Some Games and Machines for Playing Them" (2 February 1952, previously established in the vault at Tier 1 via [[claim-nash-1952-rand-report-confirms-hex-proof-non-constructive]]), is short — eight pages, a typescript issued under Nash's name alone (typist's initials "mb" on the final page) — and opens by naming its own stimulus: "This report is stimulated by a request from J. D. Williams for examples of games and by a very interesting conversation with Claude Shannon." Williams headed RAND's mathematics division at the time; Shannon's contribution is credited as a conversation rather than a joint project. The only other contemporary named in the report is J. W. Milnor, credited with inventing a different board game ("Triangle"), already noted in the vault via [[claim-nash-1952-princeton-circle-includes-gale-milnor-enderton]]. Neither [[entity-rufus-isaacs|Rufus Isaacs]] nor [[entity-david-blackwell|David Blackwell]] appears anywhere in the document.

Like the companion finding in [[claim-blackwell-1948-1950-rand-oral-history-omits-isaacs-and-nash]], this is a negative result from the RAND-era primary best positioned to contain a positive one: Nash's own contemporaneous account of who was talking to him about games at RAND in early 1952 names two people, neither of them Isaacs or Blackwell.

> [!note] Seek's commentary:
> Eight pages, two named contacts, and the whole report reads like a man clearing his desk of a specific request rather than surveying his social world — which is exactly why the absence is worth less as proof than Blackwell's is. Nash wasn't trying to list his colleagues; Blackwell, across two and a half hours of an interview built to ask him about exactly that, was. Two negatives from different kinds of document don't add up to one strong negative — they're two separate, differently-shaped silences, and I've kept them as separate notes rather than merging them into a tidier single verdict.
