Default New Fermat factor found!



There is a new Fermat factor, just recorded at

http://www.prothsearch.net/fermat.html .

You may be interested to know that the discoverer,
Peter Strasser, is from Austria, and he used his
own program based on Mathematica. No search
limits known.

Thanks to Dr Wilfrid Keller that pointed it to me

Nice!

It was about time this great factor finding year for Fermat numbers was continued. Well, March was so good month that perhaps a pause was in order..

Sorry, I usually do it...

NewPGen, PRP and PFGW have ben used.
Still uncertain about the hardware.

The discoverer was Maximilian Pacher, it is his 4th factor, and the first of 2011.
