the 13th smallest prime number. The next is 43, making both twin primes. the sum of the first six prime numbers (2 + 3 + 5 + 7 + 11 + 13). the 12th supersingular prime [1] a Newman–Shanks–Williams prime. [2] the smallest Sophie Germain prime to start a Cunningham chain of the first kind of three terms, {41, 83, 167}.
For example, 3 is a Mersenne prime as it is a prime number and is expressible as 2 2 − 1. [ 1 ] [ 2 ] The exponents p corresponding to Mersenne primes must themselves be prime, although the vast majority of primes p do not lead to Mersenne primes—for example, 2 11 − 1 = 2047 = 23 × 89 .
That is, it is a prime number of the form M n = 2 n − 1 for some integer n. They are named after Marin Mersenne, a French Minim friar, who studied them in the early 17th century. If n is a composite number then so is 2 n − 1. Therefore, an equivalent definition of the Mersenne primes is that they are the prime numbers of the form M p = 2 p ...
43 is a Heegner number. [4] 43 is the largest prime which divides the order of the Janko group J 4. 43 is a repdigit in base 6 (111). 43 is the largest natural number that is not an (original) McNugget number. [5] 43 is the smallest prime number expressible as the sum of 2, 3, 4, or 5 different primes: 43 = 41 + 2; 43 = 11 + 13 + 19; 43 = 2 ...

Ω(n), the prime omega function, is the number of prime factors of n counted with multiplicity (so it is the sum of all prime factor multiplicities). A prime number has Ω(n) = 1. The first: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 (sequence A000040 in the OEIS). There are many special types of prime numbers. A composite number has Ω(n) > 1.
