GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) The percentage of positive integers that are prime is 0%. That is, if (n) is the number of primes less than n, then as n gets larger and larger, (n)/n gets closer and closer to 0 (the limit is 0). [Caldwell] The Prime Meridian is located at 0 degrees longitude. [Rupinski] There are 0 primes p in which 0 == m mod p, where m is another prime. Of course, this is a restatement of the definition of primes. [Nicholson] Zero is nonprime and noncomposite. In any ring, for every prime there is another prime which can be added to it to get 0. Discussion of the natural primes, by contrast, does not require knowledge of 0's existence. [Merickel] Zero is the smallest of the kdigit numbers whose digit(s) are the number of distinct prime factors in each of the following k integers. The sequence begins 0, 1, 12, 21, 22422, 24223, 33333, 34441524, 4242436235, 23443535352, 34462443242, 35256523324, 4341535435353, 4645441523344, 5244526446515, 5335524234335, ... .
