Table of n, a(n) for n=1..38.

Example

The first row in A227739 (please see its Example section) that sums to 6 occurs as its row 8 (= A227368(6)). The corresponding partition {3+3} contains only equal parts, thus 6 is a member of this sequence. The first row in A227739 that sums to 5 occurs as its row 9 (= A227368(5)). The corresponding partition {1+2+2} contains more than just one kind of summands, thus 5 do not occur in this sequence.
