• Triangle read by rows: T(0,0)=1; T(n,k) is the coefficient of x^k in the polynomial (-1)^n*p(n,x), where p(n,x) is the characteristic polynomial of the n X n tridiagonal matrix with 3's on the main diagonal and -1's on the super- and subdiagonal (n >= 1; 0 <= k <= n).at n=31A123965
• Duplicate of A123965.at n=31A124025
• Numerator of Hermite(n, 5/18).at n=3A159546
• Expansion of Product_{k>=2} (1 - x^k)^k.at n=29A298599
• Sequence composed of consecutive square matrices A(d) with dimension d=1,2,3,... Matrix elements are arranged by increasing row index i, and, within fixed i, by increasing column index j. Each block A(d) is related to the inverse of a class of integer Vandermonde matrices.at n=68A347781
