Upper triangle of Catalan Number Wall. A78920

Array read by ascending antidiagonals: A(n,k) is the determinant of the n-th order Hankel matrix of Catalan numbers M(n) whose generic element is given by M(i,j) = A000108(i+j+k) with i,j = 0, ..., n-1. A368025

Triangle read by rows, giving Kekulé numbers for certain benzenoids (see the Cyvin-Gutman book for details). A123352

Number of 4-tuples (p₁, p₂, ..., p₄) of Dyck paths of semilength n, such that each p_i is never below p_i-1. A6150

a(n) = (1/(1!*2!*3!*4!))*∑_{1 <= x₁, x₂, x₃, x₄ <= n} |det V(x₁,x₂,x₃,x₄)|, where V(x₁,x₂,x₃,x₄) is the Vandermonde matrix of order 4. A133111
