• Triangle T, read by rows, such that column k equals column 0 of T^(k+1), where column 0 of T allows the n-th row sums to be zero for n>0 and where T^k is the k-th power of T as a lower triangular matrix.at n=46A101897
• Column 1 of triangular matrix A101897, in which column k equals column 0 of A101897^(k+1) and where the n-th row sums are zero for n>0.at n=8A101898
