666 is also the sum of the squares of the first sevenprimes(22 + 32 + 52 + 72 + 112 + 132 + 172),[8][11] while the number oftwin primes less than66 + 666 is 666.[12]
TheRoman numeral for 666, DCLXVI, has exactly one occurrence of all symbols whose value is less than 1000 in decreasing order (D = 500, C = 100, L = 50, X = 10, V = 5, I = 1).[8]
In theTextus Receptus manuscripts of theNew Testament, theBook of Revelation (13:17–18) cryptically asserts 666 to be "the man's number" or "the number of a man" (depending on how the text is translated) associated withthe Beast, an antagonistic creature that appears briefly about two-thirds into the apocalyptic vision. Some manuscripts[which?] of the originalKoine Greek use the symbols χξϛchixistigma (or χξϝ with adigamma), while other manuscripts spell out the number in words.[17]
In modern popular culture, 666 has become one of the most widely recognized symbols for theAntichrist or, alternativelySatanism. Earnest references to the number occur both amongapocalypticist Christian groups and in explicitly anti-Christian subcultures.References in contemporary Western art or literature are, more likely than not, intentional references tothe Beast symbolism. Such popular references are therefore too numerous to list.
It is common to see the symbolic role of theinteger 666 transferred to thenumerical 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 ashexakosioihexekontahexaphobia.
There is a broad consensus in contemporary scholarship that the number of the beast refers to theRoman emperorNero, who reigned from 55 to 68 AD.[18][19] The Greek version of his name (Νέρων Καῖσαρ, "Neron Kaisar") transliterates into Hebrew as נרון קסר (NRON QSR), and, usinggematria, yields a numerical value of 666. His Latin name, "Nero Caesar", transliterated asנרו קסר (NRO QSR), produces the number616 instead, which is also cited as the Number of the Beast in some early biblical manuscripts.[20][21]

Is the sum of all the numbers on aroulette wheel (0 through 36).[22] This is acorollary of the fact that the number is aTriangular number, as mentioned earlier.
Was a winning lottery number in the1980 Pennsylvania Lottery scandal, in which equipment was tampered to favor a4 or6 as each of the three individual random digits.[23]
Was the original name of the MacintoshSevenDust computer virus that was discovered in 1998.[citation needed] It is also the name of an extension that SevenDust can add to an uninfected Macintosh.[24]
InChinese numerology, the number is considered to be lucky and is often displayed in shop windows and neon signs.[27][28] In China, 666 can mean "everything goes smoothly" (the number six has the same pronunciation as the character 溜, which means "smooth".[29]
Where,sin(666°) = cos(216°) = −φ/2, also equivalently−cos(36°).
^149 and 151 also generate a twin-prime sum equal to300, which is the 24thtriangular number.
^It is the number11110...109877666779011...011111 (241 digits long), with an equal amount of digits (119) that precede and follow a central 666string (that also contains all sixes in the number). It is the twenty-seventhindexed member within the sequence of unique primes (where 33 = 27).
