%N A partition product of Stirling_2 type [parameter k = -6] with biggest-part statistic (triangle read by rows).
%C Partition product of prod_{j=0..n-1}((k + 1)*j - 1) and n! at k = -6,
%C summed over parts with equal biggest part (see the Luschny link).
%C Underlying partition triangle is A134278.
%C Same partition product with length statistic is A049385.
%C Diagonal a(A000217) = A008548.
%C Row sum is A049412.
