OEIS Sequences

Triangle read by rows, T(n, k) the coefficients of some polynomials in π, for n >= 0 and 0 <= k <= n. A295517

T(n,k) = Number of n X k 0..4 arrays with each element equal to the number of its horizontal and vertical neighbors less than itself. A196430

Triangle T(n,k), 0<=k<=n, giving coefficients when output sequence O₀, O₁, O₂, ... from transformation described in A059216 is expressed in terms of input sequence I₀, I₁, I₂, ... A59718

Primes p such that q-p = 28, where q is the next prime after p. A124595

Let f(n) be the smallest prime == 1 mod n (cf. A034694). Sequence gives triangle T(j,k) = f^k(j) for 1 <= k <= j, read by rows. A83809
