OEIS Sequences

Number of 4's in all partitions of n. A24788

Expansion of 1/(1-3·x)¹⁰; 10-fold convolution of A000244 (powers of 3). A36223

a(n) = ∑_k=1..n -μ(k+1) * a(n-k), with a(0)=1. A73776

Consider all compositions (ordered partitions) of n into n parts, allowing zeros. E.g., for n = 3 we get 300, 030, 003, 210, 120, 201, 102, 021, 012, 111. Then a(n) is the total number of 1's. A97070

There exists some k>0 such that n is the product of (k + digits of n). A55482

Numbers n such that n=(d₁+4)*(d₂+4)*...*(d_k+4) where d₁ d₂ ... d_k is the decimal expansion of n. A98114

Row sums of the extended Catalan triangle A189231. A189911

a(n) = (n+1)*binomial(n+7, 7). A56001

a(n) = 3⁴ * binomial(n+3, 4). A102741

0 followed by the numerators of the reduced (A001803(n) + A001790(n)) / (2·A046161(n)). A206771
