This site is supported by donations to The OEIS Foundation.

 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. Other ways to donate

 OFFSET 1,2 COMMENTS These are exactly the positions in the infinite trunk of beanstalk (see A179016 and A213729) where the node is the larger of the two possible branches from one node below. See the explanation at example-lines. LINKS Antti Karttunen, Table of n, a(n) for n = 1..10000 FORMULA a(n) = A218773(n)+1. EXAMPLE A179016(1) = 1 is the first case where the infinite trunk has continued to the larger of two branches of the predecessor node. (In this case the predecessor node is A179016(0)=0, for which hold both 0+A000120(0)=0+0=0 (the smaller branch, leading exceptionally back to the same node) and 0+A000120(1)=0+1=1 (the larger branch). Thus the first term of this sequence is 1. A179016(2) = 3 is the second case where the infinite trunk has continued to the larger of two branches of the predecessor node (In this case the predecessor node is A179016(1)=1, for which hold both 1+A000120(2)=1+1=2 (the smaller branch) and 1+A000120(3)=1+2=3 (the larger branch). Thus the second term of this sequence is 2. PROG (Scheme): (define (A213733 n) (1+ (A218773 n))) CROSSREFS Complement of A213732. First differences: A218775. Characteristic function: A213729.
