I know this might not exactly belong here, so let me know if there's a better place to ask this.

I want to know what the smallest positive integer is that has no google search results. When I say no results I mean that http://www.google.com/search?q=[number] says "Your search - [number] - did not match any documents." and the query [number] has no commas, spaces, or other punctuation.

To make this possible, please do not write actual numbers in the comments or answers because then this post would show up in the results, invalidating the answer.

The greatest lower bound I know is 12407.

The smallest upper bound I know is the number that ends with a two preceded by 82891, and starts with 11174 (so 11 digits total).

    $10821$ "eight" $92277$ is one example. Another one is $10700$ "five" $42583$. – 2017-02-09

    Any number that doesn't show up in a given search may already show up in the next search. There's no way to tell in advance if that will be the case unless you happen to know everything that happens on the web, as well as intimate details of the implementation of the Google search engine. – 2017-02-09

    Be aware that the most random number is seventeen. Well known fact. – 2017-02-09

    Also $32$ is known to be quite wily as well. It evades mathematicians and search engines alike via camouflage. – 2017-02-09

    @WillJagy You made me curious. In which sense is $17$ "the most random number" ? – 2017-02-11

    @Peter Some say that to test a theorem of the form "For all $n\in\Bbb N$, ..." it usually suffices to test it for $n=17$ ;) – 2018-11-25
