Primefree sequences in the OEIS

[N. J. A. Sloane]

Concerning this:


Sequence An in Sloane's Online Encyclopedia of Integer Sequences
contains no primes.

THIS IS REALLY ill-defined!  There are two interpretations:
A_n as visible in the current OEIS contains no primes
or
A_n when considered in full - meaning usually all infinitely
many terms - contains no prime

Only the second version is at all interesting, but I'm afraid
it was the former that was calculated. Does anyone know?
