There were 79 unprovoked shark attacks reported around the world in the year 2000, the largest number since the International Shark Attack File began compiling statistics in 1958. [Minon]
279 is the smallest power of 2 which is greater than Avogadro's number (6.0221367*10^23). [Wu]
79 = 27 - 72. [La Haye]
The smallest prime p such that when multiplied with p-1 (78 * 79 = 6162) the result is a near-tautonymic number, i.e., in this case a concatenation of two successive numbers 61 and 62 in ascending order. Note that the first halve 61 is prime as well. [De Geest]
Illinois has stated that one may not ride in the left hand lane for more than a half mile ... potential fine of $79. [Patterson]
The square root of 79 starts with four 8's. [Axoy]
The following poetic quotation contains 79 letters: "When One made love to Zero, spheres embraced their arches and prime numbers caught their breath." Raymond Queneau (French author of the mid-20th century). [Post]
Each of the numbers 1 to 79 gives a larger number when you write out its English name and add the letters using a=1, b=2, c=3, ... (but 80 gives 74). [Hartley]
U.S. President James A. Garfield died 79 days after being shot. [Dowdy]
79 appears in Skewes' number, i.e., eee79. A number below which John E. Littlewood proved that (n) becomes greater than or equal to li(n) if we assume the Riemann hypothesis is true.
There were 79 broadcasted episodes of the original Star Trek. [McCranie]

There are 79 connected graphs with 7 edges. [Post]
The smallest prime which is arithmetic average of the two previous and two next primes. [Silva]
The number of letters in the oft-cited rhetorical remark of Fields medalist Enrico Bombieri: "The failure of the Riemann hypothesis would create havoc in the distribution of prime numbers." [Beedassy]
279 = 604462909807314587353088 is the smallest pandigital number of the form 2 to the power of prime. [Poo Sung]
The largest known natural number that cannot be expressed as a sum of products of two successive primes. [Capelle]
Subtract 79 from 7!+9! and you will have another emirp. [Silva]
The largest 2-digit integer N such that N, 4*N and 5*N are all reversals of primes. [Post]
The smallest emirp whose reversal is the next emirp after it. [Silva]
Choose two 2-digit numbers of the form n and n+2 from different decades (for our purpose two 2-digit numbers are from different decades if their leftmost digits are not equal). Now reverse the digits of these two numbers and subtract the smaller from the larger. The result is always 79. For example, 58 and 60 becomes 85 - 6 = 79. [Green]
