Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

EXAMPLE

A179016(0) = 0 is the first case where the next term A179016(2) = 1 is the larger of two branches from 0 (the smaller branch in this case being 0 itself, as 0 = 0+A000120(0)), thus the first term of this sequence is 0.

A179016(1) = 1 is the second case where the next term A179016(3) = 3 is the larger of two branches from 1 (the smaller branch in this case being 2, as 2 = 1+A000120(2), 2 being a leaf node, one of the terms of A055938), thus the second term of this sequence is 1.
