It is also the largest known prime of any kind. You sound like you already know some stuff about Mersenne primes, so I won't elaborate. -Ken "Dr." Math

I have now found from another source that the latest Mersenne Prime known is 2^859433, which is the 33rd. However the discovery date is in question, being either in 1993 or 1994. Do you have a way to check on the proper date? I appreciate your help and think that the Dr. Math idea is a good one! Al

The range between M216091 and M859433 has not been exhaustively searched yet, though it is known that M216091 is indeed the 31st Marsenne prime. Perhaps soon we'll be able to say for sure if M859433 is indeed the 33rd Marsenne prime. For more on prime numbers, see the Dr. Math FAQ at http://mathforum.org/dr.math/faq/
