A ''partition'' of a positive integer ''n'' is a multiset of positive integers that add up to exactly ''n'', and an ''integer partition'' of a multiset ''S'' of integers is defined as the multiset union of partitions of integers in ''S''.

Two multisets are the same provided they contain the same elements with the same multiplicities. For example, {1, 2, 3, 3} = {3, 1, 3, 2}, but {1, 2, 3, 3} ≠ {1, 2, 3, 3, 3}.
