%N Number of ways to tile the diagram of the integer partition with Heinz number n using connected skew partitions.

%C The diagram of a connected skew partition is required to be connected as a polyomino but can have empty rows or columns. The Heinz number of an integer partition (y_1,...,y_k) is prime(y_1)*...*prime(y_k).
