the application "primegen" works or not?
What does it find or what can be found by it?

It does work, but it is dreadfully slow :( Primegen finds any primes in a given range of 100,000 (50,000 candidates)! Unfortunantly Rytis has been busy with the LLR work, so there hasn't been time to make a faster application!

Regards!

My understanding is that the primegen application generates lists of sequential prime numbers. The goal is to build a comprehensive list of prime numbers from the smallest number on up. The lists are available as DVD ISO images downloaded via torrent.

By contrast, the LLR-based searches (Twin Prime, Cullen, and Woodall searches) attempt to find primes of a specific mathematical form. These primes are much much larger than those generated by primegen, enough to break world records of the largest primes of their respective forms.
