33. A NEW
RESULT CONCERNING A
MERSENNE NUMBER.—On
2 December 1944 I finished the proof that the Mersenne number
M167 is composite;
see
MTAC, p. 333.
Hence there now remain only four of
these numbers Mp
(p = 193, 199, 227, 229) whose character is unknown. The
method of testing primality was the same as that described in Nat.
Acad. Sci., Proc., v. 30, Oct. 1944,
p. 314-316.
