Sophie Germain Prime Search found World Record twin primes [pdf]
- chx 10y agoIt's incredibly fascinating how very simple constructs like primes have such complexity to them. It's very easy for a 14 year old to formulate questions relating to primes that noone can answer.
- labster 10y agoNoone is a pretty smart guy. But there are questions that no one, not even he, can answer.
- jason_slack 10y agowhat I find interesting is the amount of computing power that it takes to calculate. Edit: As an after thought, there are recordings of million digit prime numbers: http://www.primegrid.com/download/SR5-180062.pdf http://www.primegrid.com/download/SR5-180062.pdf

- gr3yh47 10y agothis is a great example of the title change rule making a title worse i think taglines/subtitles/subject sentences should be eligible for titles too
- pavel_lishin 10y agoAre there chains of Sophie Germain primes? e.g., p is prime 2p + 1 is prime 2(2p + 1) + 1 is prime...
- teraflop 10y agoWikipedia says these are called Cunningham chains: https://en.wikipedia.org/wiki/Cunningham_chain https://en.wikipedia.org/wiki/Cunningham_chain There are no infinite chains, but there are conjectured to be inifinitely many finite chains of every possible length.
