Comments

The row sums resulting from the defined multiplication yields A038675.

A178301 is a triangular sub-array of A178300 times A125108

since A007318 is a sub-array of A125108.

Examples

			A125108(7) = 2 and appears on row five of A125108 so
A178300(5) times A125108(7) is 4*2 =8.
As a cross-check, note that A178301 = 1,4,19,96,...
and with the additional 8 in column 4 we have a(n) = 1,4,19,104,...
