OEIS Sequences

T(n,k) is the number permutations p of [n] that are j-dist-increasing for exactly k distinct values j in [n], where p is j-dist-increasing if j>=0 and p(i)<p(i+j) for all i in [n-j]; triangle T(n,k), n>=0, 0<=k<=n, read by rows. A370506

Irregular triangular array read by rows: row n shows the coefficients of the irreducible polynomial p(u) when the expansion of the n-th derivative of tan(x) is expressed in the form 2^q*(1 + u²)*p(u) if n is odd, and 2^q*u*(1 + u²)*p(u) if n is even, where u = tan(x). A392676
