COMMENTS
An integer partition of n is a finite, nonincreasing sequence of positive integers (parts) summing to n. It is strict if the parts are all different. Integer partitions and strict integer partitions are counted by A000041 and A000009 respectively.
Conjecture: This sequence is finite.
Conjecture: The analogous sequence for non-strict partitions is: 0, 1, 2.
Next term > 5*10^4 if it exists. - Seiichi Manyama, Jan 12 2020
EXAMPLE
The strict integer partitions of the initial terms:
(1) (2) (3) (4) (6) (9)
(2,1) (3,1) (4,2) (5,4)
(5,1) (6,3)
(3,2,1) (7,2)
(8,1)
(4,3,2)
(5,3,1)
(6,2,1)
