Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%Y Cf. A255415 (only every eleventh term of this sequence, starting from 11).
%Y Differs from A003309(n+5) for the first time at n=12, as a(12) = 55, the first nonludic number to be removed at stage 5 of the sieve, which is missing from A003309.
