[QUOTE=axn;242370]Unless that line itself is checksum protected to prevent/detect tampering, I can hand edit the values to something ridiculously big*. Now _that_ would be open to abuse.

*Find the largest factor of p-1. Set my B1 = that factor - 1. Then set B2 = 10000 * that factor.
For eg:- 9125624223117137685847-1 = 2*3*13*109*5392193*199056357361
Set B1 = 199056357360 and B2 = 1990563573600000. Watch the credits roll in :smile:[/QUOTE]Well if PrimeNet-credits == dollars then it might be worthwhile to some people to do that. But currently there is no point to amassing false credit. You'd just make yourself look stupid. [size=1]Or in my case -- stupider.[/size]

I would not mind a checksum per complete result, not just for the last line. But I'm also OK with the way it is right now. I think it is better to have a successful run (i.e. find a factor) than having the credit account bigger than the factors I find.

What do you use to factor the (factors-1)? prime95 isn't doing that, is it?

There are a number of programs freely available. I used PARI/GP. msieve and yafu can do much harder factorizations.

Another simple way to do it is to [URL="http://factordb.com/index.php?query=9125624223117137685847-1"]look it up[/URL] at factordb.com. It does easy factorizations like that near-instantly when you ask for the page.
