Transforms any diagonal of A096751 (square table of n-dimensional partitions) into the next lower diagonal in the table. It is not yet certain if this triangle contains negative terms.

Examples

			The main diagonal of A096751: {1,1,3,10,45,216,...} (A096752),
is transformed into the secondary diagonal: {1,1,4,15,71,357,...},
as demonstrated by the dot product of row #5 with A096752:
[0,26,10,4,1,1]*[1,1,3,10,45,216] = 357.
Rows begin:
[1],
[0,1],
[0,1,1],
[0,2,1,1],
[0,7,3,1,1],
