OEIS Sequences

Dirichlet inverse of Čiurlionis sequence, A342002. A342417

G.f. satisfies A(x) = 1 + x·A(x)² / (1 + x·A(x)³). A363982

a(n) = A325977(A228058(n)). A389217

The sequence is {a(n), n>=0}, the concatenation of the binary expansions of the absolute values |a(n)| is {b(n), n>=0}; start with a(0)=0; thereafter a(n) = a(n-1)+n if b(n-1)=0, otherwise a(n) = a(n-1)-n. A309217

Dirichlet convolution of A000027 (the identity function) with the Dirichlet inverse of the inverse permutation of EKG-permutation. A349616

a(0) = 1; a(n) = ∑_{k=0..floor((n-1)/2)} (-3)^k * a(k) * a(n-2·k-1). A352010

Sequence with Hankel transform equal to the Somos-4 sequence A006769(n+2). A178072

Expansion of e.g.f. arctan(log(x+1)/exp(x)). A13563

a(n) = μ(n)*prime(n). A62007

Expansion of x*(1+2·x+3·x²+4·x³+4·x⁴)/(1+x+x²+x³-x⁵). A122520
