OEIS Sequences

Number of 6-cycles in the n-polygon diagonal intersection graph. A300554

Triangle read by rows: T(n, n-k) = number of k-faces of the concertina n-cube. A300700

G.f. satisfies: A(x) = A(x² - x³)/(1-x). A251659

Array read by descending antidiagonals: T(h,k) is the number of paths consisting of steps from (0,0) to (h,k) such that each step has length 1 directed up or right and no up-step crosses the line y = 3x/4. (Thus a path crosses the line only at lattice points and on right-steps.) A47130

Partial sums of A283131. A283144

Number of (n+2)X4 0..1 arrays with every 3X3 subblock having three equal elements in a row horizontally, vertically, diagonally or antidiagonally at least two different ways, and new values 0..1 introduced in row major order. A204965
