COMMENTS

A permutation of the positive integers.  See A183079 and A183209.  Leftmost branch: A034472.  Rightmost branch: A061419.

LINKS

Table of n, a(n) for n=1..65.

FORMULA

Let L(n)=3n-2.

Let U(n)=A007494(n); U is the complement of L.

The tree-array T(n,k) is then given by rows:

T(0,0)=1; T(1,0)=2;

T(n,2j)=L(T(n-1),j);

T(n,2j+1)=U(T(n-1),j);

for j=0,1,...,2^(n-1)-1, n>=2.
