 OFFSET 1,2 COMMENTS We start with 1. Then for each positive integer j the sequence lists the partitions of j that do not contain 1 as a part, in lexicographical order. Then the sequence lists the partitions of j-1 together with one part of size 1 as the last part of that partition. Then the partitions of j-2 together with two parts of size 1, and so on. LINKS EXAMPLE Written as an irregular triangle, in which row n lists the partitions of n, the sequence begins: {1}; {2},{1,1}; {3},{2,1},{1,1,1}; {2,2},{4},{3,1},{2,1,1},{1,1,1,1}; {3,2},{5},{2,2,1},{4,1},{3,1,1},{2,1,1,1},{1,1,1,1,1}}; {2,2,2},{4,2},{3,3},{6},{3,2,1},{5,1},{2,2,1,1},{4,1,1},{3,1,1,1},{2,1,1,1,1},{1,1,1,1,1,1}; ...
