OEIS Sequences

Total number of prime parts in all partitions of n. A37032

Number of partitions p of n not including round(mean(p)) as a part. (This is "Mathematica round"; for round(x) defined as floor(x + 1/2), see A241734.) A241339

Schoenheim bound L₁(n,6,5). A36833

Expansion of 1/(1 - 4·x/(1-x))^3/2. A377197

Triangle interpolating the swinging factorial (A056040) restricted to odd indices with its binomial transform. Same as interpolating the β numbers 1/β(n,n) (A002457) with (A163869). Triangle read by rows, for n >= 0, k >= 0. A163842

Expansion of sqrt((1-x) / (1-5·x)⁵). A387228

∏_n>=1 (1 + a(n)*xⁿ) = 1 + ∑_n>=1 σ(n)*xⁿ, where σ = A000203. A353924

Number of partitions p of n such that round(mean(p)) is not a part of p; here, round(x) means floor(x + 1/2). A241734
