which program

[maniacken]

which program do you use for sieving above 2^50.

[vjs]

There are a couple programs to sieve above 2^50, sobsieve (i think) and nbegone...

However these programs are ALOT slower than proth and factor density decrease with increasing p. There are really alot of good ranges below 2^50, left I'd strongly suggest you stay below 2^50, but to each his own.

Why don't you just try to fill that entire gap that would be cool.

875000-899500 Maniacken

it was my plan on doing 875000-899500 Maniacken eventually.
but was just wondering about the future.

happy sieving.

The future for sieve my favorite topic...

Well we are currently about a 9 months - a year away from 2^50 ( my estimates), from the limit of the current proth program...

Hopefull before then we will have another faster program, or we can modify proth to work above 2^50.

The other possibility is to sieve n>20 or recheck some of the low T values, until another program become avaliable. Regardless before then we have alot of work to go, and sieving IMHO is where to start.
