COMMENTS

Row n lists the first A000041(n) terms of A141285.
The representation of the partitions (for fixed n) is as (weakly) decreasing lists of parts, the order between individual partitions (for the same n) is colexicographic, see example.  Joerg Arndt, Sep 13 2013

EXAMPLE

For n = 5 the partitions of 5 in colexicographic order are:
1+1+1+1+1
2+1+1+1
3+1+1
2+2+1
4+1
3+2
5
so the fifth row is the largest in each partition: 1,2,3,2,4,3,5
