COMMENTS
| The combinatorial limit of the rows is the sequence of nonnegative integers.

FORMULA
| For k>=0, the number of k's in row m is [(k+1)/m].
|
|

EXAMPLE
| The northwest corner includes
m\n 1 2 3 4 5 6 7 8 9 10 ...
----------------------------
1 | 0 1 1 2 2 2 3 3 3 3 ...
2 | 0 1 2 2 3 3 4 4 4 5 ...
3 | 0 1 2 3 3 4 4 5 5 6 ...
4 | 0 1 2 3 4 4 5 5 6 6 ...
5 | 0 1 2 3 4 5 5 6 6 7 ...
Row m=0, for example, consists of the numbers i+j (i>=0, j>=0), sorted.
