In 1977, Harold Edwards wrote: “He [Fermat] went so far as to say, later in his life, that he could prove that these numbers were all prime” – which is far from obvious to Eric Temple Bell, who makes the remark. But Edwards continues: “I do not see any other interpretation of this letter to Carcavi.” Why do many mathematicians may read : “Then I proved that ...”? To have a very good argument and say that Fermat was not reliable? Anyway, Bell did not share this opinion. The fact that Fermat gives us the choice between two options should be noted. Eventually it's this formulation for Huygens that will become after his death the most famous of his remarks on these Fermat numbers.
