%N A109461 Mersenne's original list of "Mersenne" exponents.
%C A109461 Primes appearing in Mersenne's original list (Cogitata Physica-Mathematica, 
               1644) that attempted to list all p such that 2^p-1 is prime (now 
               known as Mersenne primes). Compared to the correct list of exponents 
               that produce Mersenne primes (A000043), this list leaves out the 
               correct values 61,89 and 107 and includes the incorrect values 67 
               and 257.
%Y A109461 Cf. A000043.
