%N Multiply the irregular Array A125108 by A178300;compute a(n)the vertical sums.

%C The row sums resulting from the defined multiplication yields A038675.

%C A178301 is a triangular sub-array of A178300 times A125108

%C since A007318 is a sub-array of A125108.

%e A125108(7) = 2 and appears on row five of A125108 so

%e A178300(5) times A125108(7) is 4*2 =8.

%e As a cross-check, note that A178301 = 1,4,19,96,...

%e and with the additional 8 in column 4 we have a(n) = 1,4,19,104,...
