Meanwhile, back in the archives: on page 252 of
Rouse Ball indicates that Mersenne may
have condered 2^p - 1 to be prime for p = 1:
"In the preface to the Cogitata a statement is made about
perfect numbers, which implies that the only values of p not
greater than 257 which make N prime, where N = 2^p - 1, are
1, 2, 3, 5, 7, 13, 17, 19, 31, 67, 127, and 257.."
However, Chris's students should check the original Latin for this.
So far they are expected to be adept in Greek, Latin, Italian,
German, French and English. Maybe Euler wrote something
relevant in Russian:
