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.

1, 1, 2, 3, 1, 2, 3, 3, 4, 5, 6, 1, 2, 3, 4, 3, 4, 5, 5, 6, 7, 6, 7, 8, 9, 10, 1, 2, 3, 4, 5, 3, 4, 5, 6, 5, 6, 7, 7, 8, 9, 6, 7, 8, 8, 9, 10, 9, 10, 11, 12, 10, 11, 12, 13, 14, 15, 1, 2, 3, 4, 5, 6, 3, 4, 5, 6, 7, 5, 6, 7, 8, 7, 8, 9, 9, 10, 11, 6, 7, 8, 9, 8

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:
