139 and 149 are the first consecutive primes differing by 10. [Wells]
3139 + 2 is prime.
Stirling's formula in terms of the gamma function contains the prime number 139.
139 divides the sum of the first 139 composite numbers. [Honaker]
The first prime which has the same end-digit as its
consecutive prime. [Silva]
The largest prime factor among the smallest pair of odd amicable numbers.
The smallest prime that contains one prime digit, one composite
digit, and one digit that is neither prime nor composite. [Brown]
The smallest prime factor of the smallest multidigit composite Lucas number with a prime index.
The number of chromatically unique simple graphs on seven nodes. [Post]
STB 139 is the cryptic name for a nightspot located in the
Rippongi district of Tokyo, Japan.
In 1975, Pomerance showed that the second largest prime

139 = 9*8+7*6+5*4+3*2-1. [Silva]
The smallest prime formed by concatenating all divisors of
a composite number. [Silva]
The binary expansion 10001011 of 139 is a de Bruijn sequence of order 3 on 2 digits. [Poo Sung]
139*p is a zeroless pandigital biprime, i.e., a prime p formed by the remaining 6=3! digits 2, 4, 5, 6, 7, 8 has 120=5! possible "candidates" (because 7 has to be final digit) and 5^2 solutions. The smallest is p=248657, the largest p=865247. Note that starting parts 24=4! and 865 simply change places in these solutions! [Zschorn]
The largest prime, less than a googol, formed by
concatenating in ascending order the first n powers of 3
(n=3). Note that for n=2 we take the smallest such prime
(emirp). [Loungrides]
