Predict the exponent and/or the date it will be found. I'll guess 50M in September 2009.

A pointless exercize.

This thread is not intended to be something like "exact maths", it is a game just for fun.

(and fun is often pointless, but it's funny.)

No need to be a killjoy.

I suspect that the Mersenne Primes will be so densely located in these ranges and higher. So, around only 50 million or slightly less than that within the next 6 to 9 months is thus my estimate!
