    I bet there’s a bigger one /s. Cool to see numbers on tildes. Cool to see a new mersenne prime!

    Only asking this since it’s a video: as the headline suggests a single number being big news, how long does it currently take for new prime numbers to be discovered? Is it like a yearly event?

        Notably that list is for a specific kind of prime number (and that 2018 Mersenne prime was the largest prime number before this new one), but discovery of new primes in general is more common and several others currently among the 20 largest known primes were found in the past year.

      Along with this being the first new prime in a while, the video explains it's also novel because of how it was calculated, using GPUs.

        Someone should make some kind of distributed compute system with rewards for crunching numbers like this ;) Edit; lol it actually is distributed compute with proof of work, makes sense for the...
