GIMPS Project Discovers Largest Known Prime Number
so I didn't know this, but got curious about how many known prime there are - I knew there were infinite primes, but thought that there would be some concrete list of all the primes that we had discovered somewhere - but apparently not<p><a href="https://math.stackexchange.com/questions/272791/how-many-prime-numbers-are-known" rel="nofollow">https://math.stackexchange.com/questions/272791/how-many-pri...</a><p>> Nobody's really keeping count. ... There are very many hundred-digit primes to find. We could cover the Earth in harddisks full of distinct hundred-digit primes to a height of hundreds of meters, without even making a dent in the supply of hundred-digit primes.
