twin prime, but sieving n instead of k. Possible?
I have someone who I trust that says that a certain k should be dense with primes based on his Number Theory research(he's working on a paper). I was wondering if there's a program to sieve twin primes, but sieve n instead of k, which is what I think newpgen does.

that's right, newpgen does:
choose as type "Twin" and fill base, n, kmin and kmax (you can check "include even values of k" too to search more candidates and more chance to find a twin).

Or, you could just ask geoff to code something up specifically for twins  shouldn't be /that/ much of a big deal. Last fiddled with by axn on 20071123 at 22:22
