As detailed on Wiki/TheOtherWiki [[ here]], the number 47 has become an in joke among groups of mathematicians and screenwriters, improbable as the crossover may seem.

(it's a [[NumerologicalMotif prime number]], by the way)
* Pomona College, if not the TropeNamer, is at least the TropeCodifier, as seen [[ here]]
* ''Franchise/StarTrek'' had a Pomona graduate and member of the society Joe Menosky write several episodes of [[Series/StarTrekTheNextGeneration TNG]] and ''[[Series/StarTrekVoyager Voyager]]''. The trope caught on with the other writers, to the point that the number 47 has a page on on the Star Trek [[ wiki]].
* J.J. Abrams picked this up and uses it in his series, most prominently in ''{{Series/Revolution}}'' and ''{{Series/Fringe}}''. He's also brought it to ''Franchise/StarWars'', where it's now being used over [[Film/THX1138 1138]].
* The protagonist of the ''VideoGame/{{Hitman}}'' series.
* Averted by HK-47 from ''VideoGame/KnightsOfTheOldRepublic'', who is named after the AK-47. Same goes for the multitude of fictional guns with [[AKA47 47 in the name]].
* As most (all?) the writers of the ''Roleplay/LeagueOfIntergalacticCosmicChampions'' were ''Franchise/StarTrek'' fans 47s were a big in joke there too.
* The Wonderbolts of the ''Blog/ReadingRainbowverse'' are part of Spec Op group 47.
* The quarantine docking bay on board ''Series/RedDwarf'' is Bay 47.
