%N Permutation of natural numbers induced by the automorphism df->bf (switch from the Depth First to the Breadth First coding for the binary trees) acting on the planar binary trees encoded by A014486.
%H A. Karttunen, <a href="http://www.iki.fi/~kartturi/matikka/Nekomorphisms/gatomorf.htm">Gatomorphisms</a> (Includes the complete Scheme program for computing this sequence)
%H <a href="/index/Per#IntegerPermutation">Index entries for sequences that are permutations of the natural numbers</a>
%Y Restriction of the automorphism A072089 to the plane binary trees. Being self-embeddable, this allows us also to form the permutation A070041. Inverse permutation: A057117.
