Riecoin Breaks World Record For Largest Prime Sextuplet, Twice

An anonymous reader writes Last week, Riecoin – a project that doubles as decentralized virtual currency and a distributed computing system — quietly broke the record for the largest prime number sextuplet. This happened on November 17, 2014 at 19:50 GMT and the calculation took only 70 minutes using the massive distributed computing power of its network. This week the feat was outdone and the project beat its own record on November 24, 2014 at 20:28 GMT achieving numbers 654 digits long, 21 more than its previous record.

      Twin is two. Sex is 6.

      A sextuplet is a tight-nit group of 6; typically used to refer to the birth of 6 kids together.

      In the case of primes; it is 6 primes found sequentially which are very close to each other, where the largest prime is within 16 units distance of the smallest of the 6 primes.

      From TFA

      A prime sextuplet consists of six prime numbers packed together as tightly as possible. For sextuplets, "as tightly as possible" means that the largest is 16 plus the smallest of the numbers.

      So it's not 6 consecutive odd numbers that happen to be prime. That's impossible because of the multiples of 3 and 5. This is the lowest sextuplet: 3 5 7 11 13 17 19.

      Right :-)
      Let me see... the smallest sextuplet is from 3 to 17 but this is not a sextuplet because max - min != 16. I don't want to prove already proved theorems (nor google them) but probably the extremes of a sextuplet made of large numbers must be separated by 16 because of the multiples of 2 3 5 and 7. Maybe there are occasionally more packed sequences of 6 primes but maybe there aren't past some not too large number. Again, it's either a theorem proved by somebody else or some already made conjecture :-)
