Mersenne: Re: Factor of 2^(2^31-1)-1 found ($)

Hi Lucas Yesterday (and the day before), I went to the Illinois number theory conference. There (2nd talk of yesterday) J. P. Selfridge announced that he would give away $1000 US for any factor found of a number which ought to be prime (he provided a list). On that list was 2^(2^31-1)-1.
