OEIS Sequences

Expansion of 1/(1 - x*∏_k>=1 (1 + x^k)^k). A299167

Numbers k such that the largest unitary divisor of σ(k) that is coprime with A003961(k) is also a unitary divisor of k. A351551

T(n,k)=Number of (n+1)X(k+1) 0..3 arrays with the sum of all four elements of every 2X2 subblock equal. A237015

Expansion of e.g.f. 1/( exp(-x) - x )⁴. A379943

T(n,k)=Number of (n+1)X(n+1) 0..k arrays with the array of 2X2 subblock determinants symmetric. A187457

a(n) = 1728·n - 1320. A157263

a(n) equals the constant term in the sum of all permutations of compositions of functions (1 + k·x) for k=1..n. A277405

Triangle read by rows: T(n,k) is the number of Dyck paths with no UUU's and no DDD's, of semilength n and having k UUDUDD's starting at level 0 (0 <= k <= floor(n/3); U=(1,1), D=(1,-1)). A166295

a(n) = a(n-1) + p(n) if p(n) > a(n-1), otherwise a(n) = a(n-1) - p(n), where p is the partition function A000041 (assuming a(n) = 0 for n < 0). A331165

Least positive integer m relatively prime to n such that σ(m·n) is a fourth power, where σ(k) is the sum of the divisors of k. A334353
