This is a permutation of the positive integers.
The subsequence (a(prime(i))) is strictly increasing.
a(i) < a(prime(j)) implies i < prime(j).

EXAMPLE
a(1) = min { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ... } = 1
a(2) = min { 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ... } = 2
a(3) = min { 3, 4, 5, 6, 7, 8, 9, 10, 11, ... } = 3
a(4) = min { 5, 7, 9, 11, ... } = 5
a(5) = min { 4, 6, 7, 8, 9, 10, 11, ... } = 4
