A319793 Number of non-isomorphic connected strict multiset partitions (sets of multisets) of weight n with empty intersection. 0
1, 0, 0, 0, 1, 4, 24, 96, 412, 1607, 6348 (list; graph; refs; listen; history; text; internal format)

COMMENTS

The weight of a multiset partition is the sum of sizes of its parts. Weight is generally not the same as number of vertices.

LINKS

Table of n, a(n) for n=0..10.

EXAMPLE

Non-isomorphic representatives of the a(4) = 1 through a(5) = 4 multiset partitions:

4:  {{1},{2},{1,2}}

5: {{1},{2},{1,2,2}}

   {{1},{1,2},{2,2}}

   {{2},{3},{1,2,3}}

   {{2},{1,3},{2,3}}
