OEIS Sequences

Number of semi-lone-child-avoiding locally disjoint rooted trees with n vertices. A331872

Sum of smallest parts (counted with multiplicity) of all partitions of n into odd parts. A92313

a(n) = 2·prime(n)*prime(n+1). A69486

Total number of even parts in the last section of the set of partitions of n. A206434

For every positive integer m, let u(m) = (d(1),d(2),...,d(k)) be the unitary divisors of m. The sequence (a(n)) consists of integers of the form d(k)/d(1) + d(k-1)/d(2) + ... + d(k)/d(1). A229999

a(n) = ∑_k=1..n (-3)^floor(n/k - 1). A345035

a(n) = number of pairs {x,y} with (x,y > 1) such that x^y (= terms of A072103) has bit length n. A365930
