Self describing it's primes

[Eric Angelini]

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.
