Riecoin Breaks World Record For Largest Prime Sextuplet, Twice 51

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.

    You learn something new every day! I always thought 'sextuplets' were what you called nymphomaniac twin sisters!

      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.

        Sex is 6.

        You're wrong, though: I had sex with them more than six times! *drum hit*


        Thanks for being my 'straight man', friend! :-)

        I think you missed the joke. Entirely.

        I guess that's why they call it "nitpicking".

      But what does it REALLY mean?

      WTF is a prime sextuplet?

      A number made of six factored prime numbers?

      What is it used for?

      That would be way more interesting than "Random virtual coin network used to calculate some shit."

        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.

          ...which has, oddly, seven numbers.

          • by pmontra ( 738736 )
            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
  • What thoroughly useless information. Maybe the dice deals page has something better.

    For a network with such "massive distributed computing power", that's some pathetic servers they've got there.

    • by Anonymous Coward

      Feel free to donate any dogecoins you might have laying around for the procurement of a apocalypse-proof server.

    • by aliquis ( 678370 )

      That's a nice idea.

      A non-censored distributed forum ran for coin transactions I could have some interest in. Even better if it somehow could provide perfect anonymity.

      Fuck the freedom haters.
