WebFeb 11, 2008 · The nth prime is about n log n, the nth semiprime is about n log n / log log n. There are about n / log n primes up to n, and about n log log n / log n semiprimes up to n. For P_3, numbers with exactly 3 prime factors, the density is 2n log n / (log log n)^2. I can't remember off the top of my head (!) how that generalizes. Webmy python repository.
