Number of unoriented series-parallel networks with n elements. A339225

T(n,k)=Number of ways to reciprocally link elements of an nXk array either to themselves or to exactly one horizontal, diagonal and antidiagonal neighbor. A220621

Consider a number x. Take the sum of its digits. Repeat the process deleting the first addendum and adding the previous sum. The sequence lists the numbers that after some iterations reach the arithmetic derivative of x. A269312

Self-inverse permutation of natural numbers: a(0) = 0, a(1) = 1, and for n > 1, if A117966(n) < 0, a(n) = A117967(1+a(-(A117966(n)))), otherwise a(n) = A117968(a(A117966(n)-1)). A246211

Rotating digits of a(n)² right once still yields a square. A45877

Decimal part of n-th root of a(n) starts with digit 4. A34081

Expansion of g.f.: (1+4·x-4·x²)/(1-3·x-4·x²+4·x³). A177369

Total number of smallest parts that are also emergent parts in all partitions of n with at least one distinct part: a(n) = n + d(n) + p(n-1) + spt(n) - A000070(n) - σ(n) - 1. A220483
