OEIS Sequences

The squarefree dual of a multiset partition has, for each vertex, one block consisting of the indices (or positions) of the blocks containing that vertex, counted without multiplicity. Then a(n) is the number of non-isomorphic multiset partitions of weight n whose squarefree dual is strict (no repeated blocks). A319558

Numbers n such that the decimal expansions of both n and n² have 0 as smallest digit and 8 as largest digit. A256708

Sum of divisors of cubes. A175926

Positive integers n such that n¹⁷ + 1 is semiprime (A001358). A104494

T(n,k)=Number of nXk array permutations with each element moving zero or one space horizontally or diagonally. A189449

Compound filter (prime signature & sum of the divisors): a(n) = P(A046523(n), A000203(n)), where P(n,k) is sequence A000027 used as a pairing function. A286360

Triangle read by rows: T(n,k) counts solid partitions of n such that the maximum of planes, rows, columns and values is k. A96272

a(n) = a(n-1) + a(n-3) + a(n-4) + a(n-5) + a(n-7). A107480

Sum of the parts in the partitions of 4n into 4 parts with smallest part = 1. A239056
