decreasing the n-range in the sr5data.txt
 

Hi, at the moment we are sieving for

[code]
184 <= n <= 2000000
[/code]

According to the stats-page

the lowest n for an active test is
for riesel: 289605
and for sierpinski: 328596.
So if we start sieving in a Range
[code]
[b]250000[/b] <= n <= 2000000
[/code]
we could save some time finding factors. Is it possible to change the range? or is this a bad idea?

Bad Idea. Those n<=289000 have only been tested once. We like to have matching residues for each k,n pair. In other words, we like to test each candidate twice (at least!) and have matching residues.

OK, thank you.
