FORMULA
A026794 * A000005. (A026794 as an infinite lower triangular matrix and d(n) as a vector).
EXAMPLE
a(4) = 8 = sum of row 4 terms of triangle A137639: (7 + 2 + 0 + 1).
a(4) = 8 = (3, 1, 0, 1) dot (1, 2, 2, 3) = (3 + 2 + 0 + 3); where (3, 1, 0, 1) = row 4 of triangle A026794, the partition triangle and (1, 2, 2, 3) = the first 4 terms of A000005, d(n).
