"New" math project available with teams and stats.
The goal is to look for the lowest Sierpinski and Riesel numbers in base 5.
Here's a quote:
Stats are available here (thanks Lars)he lowest even Reisel number is mooted to be 346802 and the lowest even Sierpinski 159986. That is to say 346802.5^n-1 is always composite for every n, and 159986.5^n+1 is similarly endowed.
The Sierpinskis look the easiest to look at. We have to show there is a prime for every even k (in the power series k.5^n+1) less than k=159986 and I have checked so far up to n=18468 for all of the remaining values of k shown below. All other values of k have a prime at less than n=18468

How to run the sieve client?
Well, go here and reserve a sieve range. Then download the dat file from one of the following links:
http://base5.greenbank.org/
or
http://home.wanadoo.nl/michafleuren/...sierpinski.htm
Create a sr5work.txt and to sieve the range 50 billion to 55 billion (i.e. 50e9 to 55e9), you add a single line in sr5work.txt like this
Then start the client like this:50,55
Now is up to Bok to make some fine stats and create a special Free-DC Forum.start /min /low sr5sieve.exe
