OEIS Sequences

Expansion of (1-x)^-1/(1+2·x-x²+x³). A77922

Dirichlet inverse of A341528, where A341528(n) = n * σ(A003961(n)), and A003961 is fully multiplicative with a(prime(i)) = prime(i+1). A378228

a(1) = 0, a(2) = 0; for n > 2, a(n) - a(n-3) - a(n-5) - ... - a(n-p) = n if n is prime, otherwise = 0, where p = largest prime < n. A2123

Number of integer partitions of n with no adjacent parts having quotient >= 2. A342096

a(n) = n * σ(A003961(n)), where A003961 shifts the prime factorization of n one step towards larger primes, and σ is the sum of the divisors of n. A341528

a(n) = n*(7·n - 1)/2. A22264

a(n) = n*(n+7). A28563

Numbers whose multiset of prime factors is separable but has no alternating permutation. A345173

a(n) = n*(8·n - 3). A139273

Number of integer partitions of n with a difference < -1 and a conjugate difference < -1. A350839
