%N A319789 Number of intersecting multiset partitions of strongly normal multisets of size n.
%C A319789 A multiset is normal if it spans an initial interval of positive integers, and strongly normal if in addition its multiplicities are weakly decreasing. A multiset partition is intersecting iff no two parts are disjoint.
%e A319789 The a(1) = 1 through a(3) = 6 multiset partitions:
%e A319789 1: {{1}}
