%N Triangle read by rows, A027293 * an infinite lower triangular matrix with A147843 as the diagonal and the rest zeros.
%C Left border = the partition numbers, A000041; right border = A147843 starting (1, 2, 0, ...).
%C Row sums apparently give A000203. Check: Sum of row 6 terms = [7, 5, 3, 2, 1, 1] dot [1, 2, 0, 0, -5, 0] = [7 + 10 + 0 + 0 -5 + 0] = 12 = A000203(6).
%F Equals triangle A027293 * a lower triangular matrix with A147843 (deleting the first zero) as the right border and the rest zeros.
%F T(n,k) = A147843(k) * A027293(n,k). - _Joerg Arndt_, Dec 29 2022
