OEIS Sequences

Number of pairwise coprime compositions of n, where a singleton is not considered coprime unless it is (1). A337462

a(n) is the index of the partition that contains the divisors of n in the list of colexicographically ordered partitions of the sum of the divisors of n. A299773

G.f. satisfies A(x) = 1 + x·A(x)² / (1 - x·A(x)²)². A367237

G.f.: exp( ∑_n>=1 A203414(n)*xⁿ/n ) where A203414(n) = n·Pell(n)*∑_d∣n 1/(d·Pell(d)). A203413

a(n) = 2·p(n)*p(n+2) - p(n+1)² where p(k) = k-th prime. A324795
