What is the total number of partitions of an n-element set?

The total number of partitions of an n -element set is the Bell number Bn. The first several Bell numbers are B0 = 1, B1 = 1, B2 = 2, B3 = 5, B4 = 15, B5 = 52, and B6 = 203 (sequence A000110 in the OEIS ). Bell numbers satisfy the recursion

What is the size of the 5 partitions of N?

The 5 partitions are 1 x 30, 2 x15, 3 x 10, 5 x 6 and 2 x 3 x 5. The above implementation causes arithmetic overflow for slightly larger values of n.

## How do you find the number of partitions of a set?

Then Bell (n, k) counts the number of partitions of the set {1, 2, …, n + 1} in which the element k + 1 is the largest element that can be alone in its set. For example, Bell (3, 2) is 3, it is count of number of partitions of {1, 2, 3, 4} in which 3 is the largest singleton element.

### Is {1} a partition of {1 2 3}?

{ {1}, {2} } is not a partition of {1, 2, 3} because none of its blocks contains 3; however, it is a partition of {1, 2}. For any equivalence relation on a set X, the set of its equivalence classes is a partition of X.
