Concatenation of the sums of elements of P{1}, P{1, 2}, P{1, 2, 3}, ..., P{1, 2, 3, ..., n}; where P{A} denote the power set of set A ordered by the size of the subsets, and in each subset, following the increasing order.

EXAMPLE
Rows with power sets of set of numbers from 1 to n (without nonempty sets):
{1};
{1}, {2}, {1, 2};
{1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, {1, 2, 3};
...
Rows with the sum of elements of these subsets:
1;
1, 2, 3;
1, 2, 3, 3, 4, 5, 6;
...
Concatenation: 1, 1, 2, 3, 1, 2, 3, 3, 4, 5, 6, ...
