Is there a significance to 57 there?

• thecoffman 13y ago
  57 isn't a prime number. 3 * 19 = 57

  Yes, it isn't prime, that's the joke (I guess).

    Yes, but not in the sense that Grothendieck made a joke by saying '57', but in the sense that Grothendieck, who knows quite a bit about prime numbers, said '57' without realizing that it is composite.

      Yes, I understood it in this sense too :) Quite a character, Grothendieck.
