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.

A176169 Binary encoding of shortest and then lexicographically earliest series s(1..A176168(n)), with bits left to right indicating add (1) or subtract (0), to reproduce the series 2

OFFSET

1,3

COMMENTS

The encoding preserves the lexicographic order of series of the same length

EXAMPLE

a(3)=14, binary 1110, because the shortest series is 1 2 4 7 3, or, starting with 1, add 1, add 2, add 3, subtract 4
