%N A101033 Triangle read by rows giving the coefficients of general sum formulae 
               of n-th Lucas numbers (A000204). The k-th row (k>=1) contains T(i,
               k) for i=1 to 2*k-1, where T(i,k) satisfies L(n) = Sum_{k=1..n} Sum_{i=1..2*k-1} 
               T(i,k) * C(n-k,i-1) * n^(n-k) / (n-1)!.
