%N Irregular table T(n,k) = A164341(n,k) * A036039(n,k) read by rows.

%C The n-th row has A000041(n) columns.

%C The row sums yield A111883(n) = A000085(n)^2.

%C A000041 and A000085 are also relevant to the table defined by A104778.

%e The row lengths of A164341 and A036039 are the same, so one can multiply

%e the flattened arrays point-by-point to compute this sequence here:

%e 1..2..2..3..2..4.. A164341 times

%e 1..1..1..2..3..1.. A036039 yields

%e 1..2..2..6..6..4..

%Y Cf. A000041, A000085, A036039, A104778, A111883, A164341.
