An integer partition is knapsack if every distinct submultiset has a different sum.
I computed terms a(n) for n = 0..10000 and (6,7,7,5,5,8,7,8,2,8,6,9,6,3,7,9,5,8,3,8,6,8,6,5,6,7,7,9,1,8,7,8,6,4,6,9,6,7,3,9,5,8,7,4,6,8,6,9,2,7,7,9,5,4,7,8,6,8,2,9) is repeated continuously starting at a(32).

Examples

			The initial values count the following partitions:
   5: (5)
   6: (5,1)
   7: (5,1,1)
   7: (5,2)
   8: (5,1,1,1)
   8: (5,2,1)
   8: (5,3)
