This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 OFFSET 0,3 COMMENTS Counts the runs of consecutive ones in the binary representation of A190939. All positive integers appear in this sequence. The first A006116(n) entries contain all integers from 1 to 2^(n-1). E.g. the first 67 entries contain all integers from 1 to 8. How often each integer appears is counted by the triangle A227961.
