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.

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.
