• P_n'(3), where P_n is n-th Legendre polynomial.at n=6A002695
• Triangle read by rows: T(n,k) is the number of bicolored Dyck paths of semilength n and having k peaks of the form ud (0 <= k <= n). A bicolored Dyck path is a Dyck path in which each up-step is of two kinds: u and U.at n=38A114608
• Numbers k such that (k-1)^2 + k^2 + (k+1)^2 is a palindrome.at n=13A233007
• Triangle read by rows, T(n,k) are covariances of inverse power traces of complex Wishart matrices with parameter c=2, for n>=1 and 1<=k<=n.at n=21A272865
• E.g.f. exp( Integral B(x) dx ) = (A(x) + C(x))/8 where A(x) = 3 + Integral B(x)*C(x) dx and C(x) = 5 + Integral A(x)*B(x) dx such that A(x)^2 - 3^2 = B(x)^2 - 4^2 = C(x)^2 - 5^2.at n=5A323568
• Square array T(n,k), n >= 0, k >= 0, read by antidiagonals, where column k is the expansion of 1/(1 - 2*k*x + ((k-2)*x)^2)^(3/2).at n=51A331514
