%N A126353 Triangle read by rows: matrix product of the Stirling numbers of the 
               first kind with the binomial coefficients.
%C A126353 Many well-known integer sequences arise from such a matrix product of 
               combinatorial coefficients. In the present case we have as the first 
               row A000166 = subfactorial or rencontres numbers, or derangements: 
               number of permutations of n elements with no fixed points.

%F A126353 (In Maple notation:) Matrix product B.A of matrix A[i,j]:=binomial(j-1,
               i-1) with i = 1 to p+1, j = 1 to p+1, p=8 and of matrix B[i,j]:=stirling1(j,
               i) with i from 1 to d, j from 1 to d, d=9.
