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

 Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 1,1 COMMENTS The numbers must contain both 0's and 1's. Some of these numbers only become periodic if the leading zeros of their fundamental periods are appended to the front of their binary representations. For example, the first two terms are in this sequence, because with leading zeros they become 0101 and 001001, respectively.
