The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

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 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

 OFFSET 1,1 COMMENTS More terms than usual are given in order to display the pattern. Conjecture. a(n) is either an alternating string of 11's and 00's, or exactly one of the 00's is replaced by 000.
