2, 3 and 7 are not classfied.
Zone 1: primes for which k(n) ≤ L(n) or primes classified by weight. We have the following relation:
- g(n) + 1 ≤ k(n) ≤ sqrt(l(n)) ≤ L(n) ≤ l(n) / 3
For the first 50 000 000, 82,89 % of prime numbers are classified by
weight.
Zone 2: primes for which k(n) > L(n) or primes classified by level. We have the following relations:
- L(n) < sqrt(l(n)) < k(n) ≤ l(n)
- L(n) + 2 ≤ g(n) + 1 ≤ k(n) ≤ l(n)
For the first 50 000 000, 17,11 % of prime numbers are classified by
level.
