OEIS Sequences

T(n,k)=Number of nXk 0..1 arrays with each 1 adjacent to 0, 2 or 3 king-move neighboring 1s. A296674
a(n) is the number of configurations of n indistinguishable pairs placed on the vertices of the ladder graph P2 X Pn such that all but 3 such pairs are joined by an edge. A318268
Numbers k such that (σ(k)+σ(k+1))/σ(2·k+1) is an integer, where σ = A000203. A91287
Triangle read by rows giving the number of configurations of n indistinguishable pairs placed on the vertices of the ladder graph P2 X Pn such that exactly k such pairs are joined by an edge. A325753
Numbers k such that σ(k+1)+σ(k) = σ(2k+1). A67171
Write down the numbers from 3 to infinity. Take next number, M say, that has not been crossed off. Counting through the numbers that have not yet been crossed off after that M, cross off every 5th term. Repeat, always crossing off every 5th term of those that remain. The numbers that are left form the sequence. A100586
Record indices of the ratio A002375(n) / n (Goldbach conjecture related). A137820
