Phil's guess about the primality of 91 was bettered by

Grothendieck's guess about the primality of 57:

>> One striking characteristic of Grothendieck's

mode of thinking is that it seemed to rely so little

on examples. This can be seen in the legend of the

so-called "Grothendieck prime". In a mathematical

conversation, someone suggested to Grothendieck

that they should consider a particular prime number.

"You mean an actual number?" Grothendieck

asked. The other person replied, yes, an actual

prime number. Grothendieck suggested, "All right,

take 57." <<
