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.

      But what does it REALLY mean?

      WTF is a prime sextuplet?

      A number made of six factored prime numbers?

      What is it used for?

      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 :-)

    There are rest stops at 2, 3, 5, 7, 11, 13, and so on, but 9 is not a rest stop. The first two overlapping sets of six rest stops aren't spaced the same as the rest, and thus don't have the same mathematical properties. The Riecoin compliant prime sextuplets, err, I mean rest stops on the infinite highway are {7, 11, 13, 17, 19, 23} and {97, 101, 103, 107, 109, 113}, except they are too small for cryptography.

    I suppose prime sextuplets are mostly just cool, because they're primes, and close to each other.
    Who knows, they might have applications in cryptography, image compression or whatever.
    It is possible that there are an infinite number of twin primes, but only a finite number of triplets/quadruplet/sextuplet.
