%N A326018 Heinz numbers of knapsack partitions such that no addition of one part up to the maximum is knapsack.
%C A326018 The Heinz number of an integer partition (y_1,...,y_k) is prime(y_1)*...*prime(y_k).
%C A326018 An integer partition is knapsack if every submultiset has a different sum.
%C A326018 The enumeration of these partitions by sum is given by A326016.
