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

%N 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

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

%H R. H. Hardin, <a href="/A176169/b176169.txt">Table of n, a(n) for n=1..80</a>

%e 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

%Y See A176168 for definitions

%K nonn

%O 1,3
