This article describes cardinal numbers in mathematics For cardinals in linguistics see Names of numbers in English. In Set theory, an ordinal number, or just ordinal, is the Order type of a Well-ordered set. In Mathematics, factorization ( also factorisation in British English) or factoring is the decomposition of an object (for In Mathematics, a prime number (or a prime) is a Natural number which has exactly two distinct natural number Divisors 1 In Mathematics, a divisor of an Integer n, also called a factor of n, is an integer which evenly divides n without Roman numerals are a Numeral system originating in ancient Rome, adapted from Etruscan numerals. The binary numeral system, or base-2 number system, is a Numeral system that represents numeric values using two symbols usually 0 and 1. In Mathematics and Computer science, hexadecimal (also base -, hexa, or hex) is a Numeral system with a In Mathematics, a prime number (or a prime) is a Natural number which has exactly two distinct natural number Divisors 1 In Mathematics, primorial primes are Prime numbers of the form pn # ± 1 where pn # is the 31 ( thirty-one) is the Natural number following 30 and preceding 32. A twin prime is a Prime number that differs from another prime number by Two. Twenty-nine is also the sixth Sophie Germain prime. In Number theory, a Prime number p is a Sophie Germain prime if 2 p + 1 is also prime It is also the sum of three consecutive squares, 22 + 32 + 42. It is a Lucas prime, a Pell prime and a tetranacci number. The Lucas numbers are an Integer sequence named after the mathematician François Édouard Anatole Lucas (1842&ndash1891 who studied both that sequence and the In Mathematics, the Pell numbers and companion Pell numbers (Pell-Lucas numbers are both sequences of Integers that have been known since ancient In Mathematics, the Fibonacci numbers form a Sequence defined recursively by F (0 = 0 F (1 = 1 F ( It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1. In Mathematics, an Eisenstein prime is an Eisenstein integer z = a + b\\omega\qquad(\omega = e^{2\pi i/3} that is irreducible Since 18! + 1 is a multiple of 29 but 29 is not one more than a multiple 18, 29 is a Pillai prime. A Pillai prime is a Prime number p for which there is an integer n > 0 such that the Factorial of n is one less than a multiple of 29 is also the 10th supersingular prime. If E is an Elliptic curve defined over the Rational numbers then a prime p is supersingular for E if the reduction
None of the first 29 natural numbers have more than two different prime factors. This is the longest such consecutive sequence.
29 is a Markov number, appearing in the solutions to x2 + y2 + z2 = 3xyz: {2, 5, 29}, {2, 29, 169}, {5, 29, 433}, {29, 169, 14701}, etc. A Markov number or Markoff number is a positive integer x, y or z that is part of a solution to the Markov Diophantine equation
29 is a Perrin number, preceded in the sequence by 12, 17, 22. In Mathematics, the Perrin numbers are defined by the Recurrence relation P (0 = 3 P (1 = 0 P (2 = 2
Since the greatest prime factor of 292 + 1 = 842 is 421, which is obviously more than 29 twice, 29 is a Størmer number. In mathematics a Størmer number or arc-cotangent irreducible number, named after Carl Størmer, is a positive integer n for which the greatest prime factor
