Appears in sequences

• First of three consecutive Ulam numbers (A002858) in arithmetic progression with difference 22.at n=20A068856
• Grow a binary tree using the following rules. Initially there is a single node labeled 1. At each step we add 1 to all labels less than 3. If a node has label 3 and zero or one descendants we add a new descendant labeled 1. Sequence gives sum of all labels at step n.at n=46A123015
