"In number theory and combinatorics, a partition of a positive integer n, also called an integer partition, is a way of writing n as a sum of positive integers. Two sums that differ only in the order of their summands are considered the same partition. (If order matters, the sum becomes a composition.) For example, 4 can be … Se mer The seven partitions of 5 are • 5 • 4 + 1 • 3 + 2 • 3 + 1 + 1 • 2 + 2 + 1 Se mer The partition function $${\displaystyle p(n)}$$ equals the number of possible partitions of a non-negative integer $${\displaystyle n}$$. … Se mer The rank of a partition is the largest number k such that the partition contains at least k parts of size at least k.

Nettet3.3 Partitions of Integers. [Jump to exercises] Definition 3.3.1 A partition of a positive integer n is a multiset of positive integers that sum to n. We denote the number of partitions of n by p n. . Typically a partition is written as a sum, not explicitly as a multiset. Using the usual convention that an empty sum is 0, we say that p 0 = 1 .
