OEIS Sequences

Number of augmented André 3-signed permutations: E.g.f. (1-sin(3·x))^-1/3. A7788

Array read by ascending antidiagonals: A(n, k) = k! * [x^k] (1 - sin(n·x))^-1/n for n > 0, A(0, k) = 1. A385896

Number of nX3 0..2 arrays with every row and column running average nondecreasing rightwards and downwards, and the number of instances of each value within one of each other. A200772

Antidiagonally reading the array, formed via: first, writing the primes in the first row (row₁), and forming all successive rows' elements using the previous rows' elements as: row₂(j) = row₁(j)*row₁(j+1) - row₁(j) - row₁(j+1), and so on. The first 'column' of the array, 2 1 -1 -1 -1 -1 -1 -1 ... is converted to its absolute value. A165401
