• a(n) gives the position of -n in the sequence (or tree) S generated in order by these rules: 0 is in S; if x is in S then x + 1 is in S; if nonzero x is in S then 1/x is in S; if x is in S, then i*x is in S; where duplicates are deleted as they occur.at n=13A233695
• Positions of integers in the sequence (or tree) S generated in order by these rules: 0 is in S; if x is in S then x + 1 is in S; if nonzero x is in S then 1/x is in S; if x is in S, then i*x is in S; where duplicates are deleted as they occur.at n=30A233696
• E.g.f. satisfies A(x) = exp(x + x * A(x)^2).at n=5A362694
• Maximal coefficient of (1 - x) * (1 - x^4) * (1 - x^9) * ... * (1 - x^(n^2)).at n=55A369728
