Generalized Fermat Prime Search?
 

I'd like to know if prothsearch is still active; I'd like to search also some Generalized Fermat primes but mr. Yves Gallot didn't answer to my email to reserve a range .
Do you know if it is still active ? Or any similar project ?

I assume you mean the Generalized Fermat Prime Search at [url]http://perso.wanadoo.fr/yves.gallot/primes/gfn.html[/url] and not the Proth Search at [url]http://www.prothsearch.net[/url]. AFAIK, Yves has been out of contact for over a year. Phil Carmody has helped with the GFN search (in the sieving area). He might know something. Another person who might know is Daniel Heuer.

Is [url]http://www.prothsearch.net/[/url] offering pre-sieved ranges? If so I have some slow computers that I can put on finding small proth primes. Please let me know on how to get these ranges?

Thanks,

edit: I think I figured on how to get presieved ranges. May be you can put a guide on which k's are in need of most work.

You should be able to get pre-sieved ranges from [url]http://www.prothsieve.com/[/url], although it didn't work the last time I tried.

As for "most needed", there is no such concept for the Proth Search.
