666 is the natural number following 665 and preceding 667. Base32 is a Base-32 transfer encoding using the twenty-six letters A-Z and six digits 2-7 Base 36 is a positional numeral system using 36 as the Radix. It is also an abundant number. In Mathematics, an abundant number or excessive number is a number n for which σ ( n) > 2 n. It is the sum of the first 36 natural numbers (i. e. 1 + 2 + 3 + . . . + 34 + 35 + 36 = 666), and thus a triangular number. A triangular number is the sum of the n Natural numbers from 1 to n. Since 36 is both square and triangular, 666 is the sixth number of the form n2(n2 + 1) / 2 (sequence A037270 in OEIS) and the eighth number of the form n(n + 1)(n2 + n + 2) / 8 (doubly triangular numbers, A002817). 36 ( thirty-six) is the Natural number following 35 and preceding 37. In Mathematics, a square number, sometimes also called a Perfect square, is an Integer that can be written as the square of some other The On-Line Encyclopedia of Integer Sequences ( OEIS) also cited simply as Sloane's, is an extensive searchable Database of Integer sequences
666 is the sum of the squares of the first seven prime numbers (i. In Mathematics, a prime number (or a prime) is a Natural number which has exactly two distinct natural number Divisors 1 e. 22 + 32 + 52 + 72 + 112 + 132 + 172 = 666).
The harmonic mean of the decimal digits of 666 is (trivially -- all repdigit natural numbers have this property) an integer: 3/(1/6 + 1/6 + 1/6) = 6, making 666 the 54th number with this property. In Mathematics, the harmonic mean (formerly sometimes called the subcontrary mean) is one of several kinds of Average. In Mathematics and Computer science, a digit is a symbol (a number symbol e In Recreational mathematics, a repdigit is a Natural number composed of repeated instances of the same digit most often in the decimal numeral system. The integers (from the Latin integer, literally "untouched" hence "whole" the word entire comes from the same origin but via French
In base 10, 666 is a palindromic number, a repdigit and a Smith number. A palindromic number or numeral palindrome is a 'symmetrical' number like 16461 that remains the same when its digits are reversed In Recreational mathematics, a repdigit is a Natural number composed of repeated instances of the same digit most often in the decimal numeral system. A Smith number is a Composite number for which in a given base, the sum of its digits is equal to the sum of the digits in its prime factorization A prime reciprocal magic square based on 1/149 in base 10 has a magic total of 666. A prime reciprocal magic square is a Magic square using the digits of the reciprocal of a Prime number.
The Roman numeral representation of the number 666 (DCLXVI) uses once each the Roman numeral symbols with values under 1,000, occurring in descending order of their respective values (D = 500, C = 100, L = 50, X = 10, V = 5, I = 1). Roman numerals are a Numeral system originating in ancient Rome, adapted from Etruscan numerals.
666 is a member of the Indices of prime Padovan sequence, 3, 4, 5, 7, 8, 14, 19, 30, 37, 84, 128, 469, 666, 1262, 1573, 2003, 2210, . The Padovan sequence is the Sequence of Integers P ( n) defined by the initial values P(0=P(1=P(2=1 . . (sequence A112882 in OEIS).

In the Bible, the Book of Revelation (13:17-18) cryptically asserts 666 to be "the number of a man", associated with the beast, an antagonistic creature that appears briefly about two-thirds into the apocalyptic vision. The Number of the Beast is a concept from the Book of Revelation of the New Testament of the Christian Bible. The Book of Revelation, also called Revelation to John, Apocalypse of John ( pronounced, from the Ἀποκάλυψις Ἰωάννου This article refers to the Biblical character For other uses see Beast. The author challenges the reader to figure out the symbolism of this number, a challenge that has inspired mystics and would-be prophets ever since. It is assumed by many biblical scholars to refer to Emperor Nero. Nero Claudius Caesar Augustus Germanicus ( December 15, 37 – June 9, 68) born Lucius Domitius Ahenobarbus, also called The number is arrived at by presenting Nero's name in Greek (Kaisar Neron) and transforming it into Hebrew whose letters also have a numeric value. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly The Hebrew letters would be q=60, s=100, r=200,n=50,w=6[1].
The number of people who have been proposed to be the man whose number is 666 is vast and ever growing; it usually does not demand much ingenuity to find several ways to connect one's political or religious opponent with the number 666, since there is no biblical restriction on how a connection between a man and the number may be established.
In modern popular culture, 666 has become one of the most widely recognized symbols for Satan or the Devil. Satan, ( Standard Hebrew Satan'el, English accuser) is a term that originates from the Abrahamic faiths, being traditionally mainstream Christianity, the Devil is named Satan, sometimes Lucifer. Earnest references to 666 occur both among apocalypticist Christian groups and in explicitly anti-Christian subcultures such as that surrounding some heavy metal bands; more humorous allusions to the 666 symbolism (e. g. , the Lemmings level featuring three 6's built upon "hellish" lava terrain) are mainstream. Lemmings is a puzzle computer game, developed by DMA Design and published by Psygnosis in, originally for the Commodore Amiga An appearance of the number 666 in contemporary Western art or literature is more likely than not an intentional reference to this number of the Beast symbolism. Such popular references to 666 are too numerous to list here.
It is not uncommon to see the symbolic role of the integer 666 transferred to the digit sequence 6-6-6. Some people take the satanic associations of 666 so seriously that they actively avoid things related to 666 or the digits 6-6-6. This is known as hexakosioihexekontahexaphobia. Hexakosioihexekontahexaphobia (literally "fear of the number six-hundred-sixty-six" is the fear that originates in the Biblical verse Revelation 1318 which indicates
