%N Heinz numbers of strict integer partitions with distinct differences (with the last part taken to be 0).
%C The Heinz number of an integer partition (y_1,...,y_k) is prime(y_1)*...*prime(y_k).
%C The differences of a sequence are defined as if the sequence were increasing, so for example the differences of (6,3,1) (with the last part taken to be 0) are (-3,-2,-1).
%C The enumeration of these partitions by sum is given by A320348.
