72Lévy's constant — In mathematics Lévy s constant (sometimes known as the Khinchin–Lévy constant) occurs in an expression for the asymptotic behaviour of the denominators of the convergents of continued fractions. In 1936 French mathematician Paul Lévy showed that… …
73167 (number) — 167 is the natural number following 166 and preceding 168.It is a prime number, a safe prime and an Eisenstein prime with no imaginary part and a real part of the form 3n 1. Since the next odd number, 169, is a square of a prime, 167 is a Chen… …
74Largest known prime number — The largest known prime number is the largest integer that is currently known to be a prime number.It was proven by Euclid that there are infinitely many prime numbers; thus, there is always a prime greater than the largest known prime. Many… …
75149 (number) — 149 is the natural number between 148 and 150. It is also a prime number.In mathematics149 is the 35th prime number, and with the next prime number, 151, is a twin prime, thus 149 is a Chen prime. 149 is a strong prime in the sense that it is… …
76158 (number) — 158 is an even whole number before 159 and after 157.In mathematics158 is a nontotient, since there is no integer with 158 coprimes below it. 158 is a Perrin number, appearing after 68, 90, 119.It is the number of digits in the decimal expansion… …

78Abelian root group — If G is an abelian group and P is a set of primes then G is an abelian P root group if every element in G has a p th root for every prime p in P ::gin G,pin P Rightarrow exists hin G, h^p=g;(with the product written multiplicatively)If the set of …
79Prime gap — A prime gap is the difference between two successive prime numbers. The n th prime gap, denoted g n , is the difference between the ( n +1) th and the n th prime number, i.e.: g n = p n + 1 − p n .We have g 1 = 1, g 2 = g 3 = 2, and g 4 = 4. The… …
80Constante de Landau-Ramanujan — En théorie des nombres, la constante de Landau Ramanujan apparaît dans le résultat selon lequel le nombre d entiers naturels inférieurs à x qui sont la somme de deux carrés est asymptotiquement proportionnel à Plus précisément, le nombre d… …
