EXAMPLE

When A089840(1) = A069770 (swap binary tree sides) is applied to the right subtree of a binary tree, we get A089850 = A089840(3), thus a(1)=3. When A089840(12) = A074679 is applied to the right subtree of a binary tree, we get A154121 = A089840(3655), thus a(12)=3655.

CROSSREFS

a(n) < A123694(n) for all n > 0. Used to construct A153832 and A153833.
