COMMENT
|
Right border = the partition numbers, A000041.
Left border = A000070.
Row sums = A141156.
|
|
FORMULA
|
A140207 * A000012 as infinite lower triangular matrices.
|
|
EXAMPLE
|
First few rows of the triangle are:
1;
2, 1;
4, 3, 2;
7, 6, 5, 3;
12, 11, 10, 8, 5;
19, 18, 17, 15, 12, 7;
30, 29, 28, 26, 23, 18, 11;
45, 44, 43, 41, 38, 33, 26, 15;
...
n-th row of the triangle = partial sums n-th row terms of triangle A140207 starting from the right. Example: row 3 = (7, 6, 5, 3), since row 3 of triangle A140207 = (1, 1, 2, 3).
