As with the number 23 in Robert Anton Wilson's Illuminatus! novels, there appears to be a certain metaphysical or perhaps even occult dimension to the repeated occurence of this number in the works of Terry Pratchett.
This list will no doubt be added to over the coming months, but one that immediately springs to mind in the absence of the books is that in The Last Hero, this contributor recollects that precisely fifty-seven pedigree varieties of swamp dragon are illustrated in a double-page spread.
References claimed by other contibutors and elsewhere on the Wiki have been brought together as follows:-
- In Equal Rites, when Esk is stranded in the trading settlement of Zemphis and looking for a way to get to Ankh-Morpork, she accosts a harrassed-looking trader who is counting bales of tobacco. He gets as far as "Fiftysevenfiftysevenfiftysevenwell?" before he is forced to acknowledge her presence;
- In Wyrd Sisters, Queen Grimnir the Impaler (1514-1553, 1553-1557, 1557-1562, 1562-1567 and 1568-1573) was a vampire queen of Lancre;

In its advertising campaigns and even on its product labels, the Heinz Corporation made this number its very own by proudly proclaiming "Fifty-Seven Varieties!" (Except in the universe of the Watchmen graphic novel, where observant readers noted a 58 varieties caption on the tin of beans that Rorshach consumes in the first chapter.
Fifty-seven varieties of what, exactly, are never precisely defined, (just as Cadbury's famous "glass-and-a-half of milk in every bar" is never scientifically defined according to size of the glass), but for whole generations of consumers, Heinz is synonymous with the number 57.
Among car enthusiasts, 1957 is considered a banner year for both American (last year for the two seat Ford Thunderbird, '57 Chevy, Forward-Look Chryslers) and European (last year for the Oval Window VW, first year for the Morris Minor 1000) cars.
