- Questions like this have received a fair amount of study. The
- conjectured density of quadruplets <= N is ~ C * N / (log N)^4,
- where C is expressible as an infinite product over the primes.
- This is based on probabilistic arguments, and agrees with
- numerical data, as far as we know. Using sieve methods, it can
- be shown that the number is O( N / (log N)^4 ).
