RE : Self describing it's primes

[Eric Angelini]

Hello Marc,
no, 3 and 7 are not available; start like this (c=non-prime and p=prime):
 
1
1 p
1 2
1 2 c p
1 2 4 p 
1 2 4 p c c p
1 2 4 5 c c p
1 2 4 5 c c p c p
1 2 4 5 6 c p c p
1 2 4 5 6 c p c p c p
1 2 4 5 6 8 p c p c p
1 2 4 5 6 8 p c p c p c c p
etc.
Best,
E.

	Hello SeqFans,
	
	1,2,4,5,6,8,11,12,13,14,17,18,20,23,24,25,26,29,...
	
	Read a(n) like this :
	
	"Move a(n) steps to the right and you will bump into a prime"
	
	a(n) is always the smallest unused non-prime, except when a(n) must be a prime; if so, a(n) is the smallest unused prime.
	
	Could someone check this seq, calculate some more terms and submit them to the OEIS, if of interest?
	
	Best,
	E.
