finding and sharing files
- Hello All
I have been spinning my wheels on a problem that I can not find an
easy answer. So I thought I would ask before spinning my wheels
trying to find a complicated answer.
When I first started exploring primes I thought you could just
download some files from somewhere and start working. Wrong. Not
being able to locate files I did what I think most people are doing
and that is, find or write software to generate files to work with.
At this time I have over 11 gigabytes of small primes and counting.
Which causes me to ask two questions.
1. Is there some where that I can download files for a fee or other
2. Is there some way ,without going broke, that I can post the files
I have so others do not have to duplicate work that is already done?
I would welcome what ever suggestions you may have.
Just to be clear I am talking about general primes no special forms.

that an optimized sieve can generate small primes faster
than you can read them from a disk drive.
So there's really not a lot to be gained by pre-generating huge
lists of small prime numbers.
The program 'primegen' can generate small primes very quickly,
like millions of primes per second. Google for primegen, or
