%N Table of partitions of n into distinct parts, in Mathematica ordering.
%C Reverse lexicographic order where the partitions are reprepresented as (weakly) decreasing lists of parts. [_Joerg Arndt_, Jan 25 2013]

%e The partitions of 5 into distinct parts are [5], [4,1] and [3,2], so row 5 is 5,4,1,3,2.
