Number of different strings of length n+5 obtained from "123...n" by iteratively duplicating any substring. A137740

Number of unlabeled trees on n nodes with maximum degree three and three vertices of degree three. A355024

a(1,2,3) = 1,2,3; let j = a(n-1), M(n) = ∏_{i = 1..n-2} { p a distinct prime: p | a(i), gcd(p, j) = 1 }. For n > 3, a(n) is the least novel multiple of M(n) if M(n) > 1; otherwise a(n) is the least novel multiple of A053669(j), the smallest prime which does not divide j. A368133
