777 (seven hundred [and] seventy-seven) is the natural number following 776 and preceding 778. The number 777 is significant in numerous religious and political contexts.
In mathematics
[edit]777 is an odd, composite, palindromic[1] repdigit.[2] It is also a sphenic number,[3] an extravagant number,[4] a lucky number,[5] a polite number,[6] an amenable number, and a deficient number. 777 is a congruent number,[7] as it is possible to make a right triangle with rationally numbered side lengths whose area is 777.[8]
777 is 1 + 196 + 256 + 324 —> 1² + 14² + 16² + 18² where 1, 14, 16 and 18 are the digits amid the first 7 primes, whose squares' sum is 666, one of the Beast's numbers:
666 = 4 + 9 + 25 + 49 + 121 + 169 + 289 —> 2² + 3² + 5² + 7² + 11² + 13² + 17².[9]
Religious significance
[edit]According to the Bible, Lamech, the father of Noah lived for 777 years.[10]
Christianity
[edit]According to some, 777 is a symbol of the Trinity, in contrast to 666, the number of the Beast[11].
Thelema
[edit]777 is also found in the title of the book 777 and Other Qabalistic Writings of Aleister Crowley pertaining to the law of thelema.[12]
Political significance
[edit]Afrikaner Weerstandsbeweging
[edit]The Afrikaner Resistance Movement (Afrikaner Weerstandsbeweging, AWB), a Boer-nationalist movement in South Africa, used the number 777 as part of their emblem.[13]
The number refers to a triumph of "God's number" 7 over the number of the beast.[14] On the AWB flag, the numbers are arranged in a triskelion shape, resembling the Nazi Swastika.
Computing
[edit]In Unix's chmod, change-access-mode command, the octal value 777 grants all file-access permissions to all user types in a file.
Commercial
[edit]Aviation
[edit]
Boeing, the largest manufacturer of airliners in the United States, released the Boeing 777 (commonly nicknamed the Triple Seven) in June 1995.[15] The 777 family includes the 777-200, 777-200ER, the 777-300, the 777-200LR Worldliner, the 777-300ER, and the 777 Freighter. The -100 wasn't continued in production due to loss of interest. In the 21st century, Boeing has developed what will be in use for some different airlines, called the Boeing 777X. Projects have been delayed because of COVID-19, but will return to normal production.[16]
777 Tower
[edit]777 Tower is an office building situated in the US and it was built in 1991.[17]
Gambling and luck
[edit]777 is used on most slot machines in the United States to identify a jackpot. As it is considered a lucky number, banknotes with a serial number containing 777 tend to be valued by collectors and numismatists. The US Mint and the Bureau of Engraving and Printing sells uncirculated 777 $1 bills for this reason.[18]

We have already seen two sums of squares 15² + 21² and 216² + 630² that are related to 666. Are there any other interesting sums of squares which add up to 666? You may be surprised to learn that the sum of the squares of the first seven prime numbers add up to 666. 2² + 3² + 5² + 7² + 11² + 13² + 17² = 666 ................ ................ All the numbers up to 17 except 1, 14, and 16. have now been used. Whatnhappens if I take the sum of the squares of these three numbers as well as 18? I get: 1² + 14² + 16² + 18² = 777 This is very strange indeed. The number of the Beast or Satan is 666, but 777 is the number of God. It is also well known in traditional numerology, that 6s signifies evil and 7s signifies good. ....................... ....................... ....................... 1 + 14 + 16 + 18 = 49 = 7 × 7,
