- Table (read by rows) giving the coefficients of sum formulas of n-th Lucas numbers (A000204). The k-th row (k>=1) contains T(i,k) for i=1 to k, where k=[2*n+1+(-1)^(n-1)]/4 and T(i,k) satisfies L(n) = Sum_{i=1..k} T(i,k) * n^(k-i) / (k-1)!.at n=18A101032
- Sequence is {a(0,n)}, where a(m,0)=1, a(m,n) = a(m-1,n)+a(m,n-1) and a(0,n+1) is such that a(n+1,n+1) = a(0,n).at n=9A111518
