%N A296560 Number of normal semistandard Young tableaux whose shape is the conjugate of the integer partition with Heinz number n.
%C A296560 A tableau is normal if its entries span an initial interval of positive integers. The Heinz number of an integer partition (y_1,...,y_k) is prime(y_1)*...*prime(y_k).
