%N Tree generated by 3n-2.
%C A permutation of the positive integers. See A183079 and A183209. Leftmost branch: A034472. Rightmost branch: A061419.
%F Let L(n)=3n-2.
%F Let U(n)=A007494(n); U is the complement of L.
%F The tree-array T(n,k) is then given by rows:
%F T(0,0)=1; T(1,0)=2;
%F T(n,2j)=L(T(n-1),j);
%F T(n,2j+1)=U(T(n-1),j);
%F for j=0,1,...,2^(n-1)-1, n>=2.
