%N Ordering of the numbers in the tree A183543; complement of A183544.

%F The monotonic ordering of the numbers in the set S generated by these rules: 3 is in S, and if n is in S, then -2+Floor[(n+2)r] and n+Floor[(n+2)r] are in S, where r=(1+sqrt(5))/2, the golden ratio.

%t nn=200; g=(1+5^(1/2))/2; t={3}; t0=t; While[t=Select[Union[t,-2+Floor[(t+2)g],t+Floor[(t+2)g]], #<=nn&]; t0 !=t, t0=t]; t

%Y Cf. A183542, A183543, A183544.
