  • ...anyone know the name of a theorem that proves that the average density decreases (if it exists)? This would help me immensely... Plano9

  • Has is been proven that the density of prime numbers will never increase (I think you know what I mean) as you go into larger and larger numbers?

  • I'm (attempting) to make a quadratic and no resources are making it clear on how I choose the size of the factor base to use. Can anyone help me on how to do that? Thanks, Plano9

  • 1) Which number do the most primes end in {1, 3, 7, or 9}? I'm guessing 7 but does someone know? and a similar one 2) If you input a really long stream of numbers into 6n+1 and 6n-1, which would yield more prime numbers? plus my question about what a quadtratic prime sieve does differently than a normal one...
