Hello,

It seems that there is a misprint on the page
http://www.wolfram.com/products/mathematica/usersanduses/mersenne.html
We read that "In June 1999 an international group of mathematicians,
computer scientists, and hobbyists <...> discovered that 2^6972593-1
is
prime." But it is not true:
In[3]:= PrimeQ[2^26972593 - 1]
Out[3]= False
