A Mersenne number is any number of the form 2p 1 for a natural number p. To make things a bit more pleasant, we additionally exclude 22 1, i.e. we require p > 2. It can be shown that p is then always an odd prime. locale mersenne-prime = fixes p M:: nat defines M 2 ^ p 1 assumes p-gt-2: p > 2 and prime: prime M begin lemma M-gt-6: M > …

So if n = mk, 2n ¡ 1 always has a factor 2m ¡ 1, and therefore is prime only when 2m ¡ 1 = 1. This immediately reduces to 2m = 2, or simply m = 1. Thus, if n is composite, 2n ¡1 is composite. Now we know we are only interested in numbers of the form 2p ¡1; if this number is prime then we call it a Mersenne prime. As it turns out, not every ...

We shall call any number of the form 2n 1 a Mersenne number, regardless if n is prime. For an integer m > 1, let P(m) denote the largest prime factor of m, and let P(1) = 1. We are interested in this paper in studying P(2n 1). First, we shall review what is known about P(2n 1). Schinzel [11] has shown that

which are called Mersenne prime. It is outstanding in their simplicity. • Clearly, if 2p − 1 is prime then p is prime. The number 2p − 1 is Mersenne composite if p is prime but 2p − 1 is not prime. For example, the prime number 27 − 1 = 127 is called Mersenne prime. However, the number 211 − 1 = 2047 = 23 × 89 is called

the Collatz matrices deliver a necessary criterion for prime numbers (Col-latz matrix conjecture), and Chapter 5 contains a conjecture about Collatz matrices and Mersenne prime numbers (Kaiser’s conjecture). The de nitions of Chapter 2 (2.1, 2.2, 2.3 and 2.4) are already well known to the "Collatz community". For further Informaton see: [2, 3].

1.1. Mersenne primes A Mersenne prime is a prime number that can be expressed in the form 2p − 1, where p is also a prime number. In other words, a Mersenne prime is a prime of the form M p ¼ 2p − 1, where both M p and p are prime numbers. 1.2. Mersenne composites Conversely, a Mersenne composite number is a num-

The Euclid-Euler TheoremAn even positive integer is a perfect number, that is, equals the sum of its proper divisors, if and only if it has the form 2n−1(2n −1), for some n such that 2n −1 is prime. A prime of the form 2n −1 must have n also prime, a fact sometimes known as the Cataldi–Fermat Theorem; it thus belongs to the so-called

In Section 4, we formally introduce the Generalized Mersenne Prime (GMP) R(k,p)=(pk -1)/(p-1)where R(k,p) is a prime number. In order to search for high dimensional MRGs, we propose a more efficient search algorithm designed for GMP. Using the newly proposed search algorithm, we are able to find generators in the class of DX-kwith various ...

For n ≥ 1 and t ∈ Z, if p = Φ n(t) is prime, we call p an n-th cyclotomic prime, or simply a cyclotomic prime. Note that for all primes p, we have p = Φ 1(p+1) = Φ 2(p−1), and so trivially all primes are cyclotomic primes.
