(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A079254 a(n) is taken to be the smallest positive integer greater than a(n-1) which is consistent with the condition "n is a member of the sequence if and only if a(n) is prime". 33
4, 6, 8, 11, 12, 13, 14, 17, 18, 20, 23, 29, 31, 37, 38, 39, 41, 43, 44, 47, 48, 49, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 71, 73, 74, 79, 80, 83, 89, 90, 91, 97, 101, 103, 104, 105, 106, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167 (list; graph; refs; listen; history; text; internal format)

EXAMPLE

a(1) cannot be 1 because 1 is not prime; it cannot be 2, for then 1 is not in the sequence while a(1) is prime; nor can it be 3; but 4 is possible.
