Judging from the "what is it?" on that tinyurl, it is the cross product of the mplbook's exercise 7-8 mentioned in my previous post.
It indeed has similar behavior when feeding it 2 sequences as the cross product, or to be more precise, an outer product (as you mentioned earlier) since both sequences need not have the same length. Looking at Wikipedia's definition: http://en.wikipedia.org/wiki/Outer_product then my algorithm produces the outer product when called with 2 sequences. When called with 3 sequences, it generates some kind of 3-way outer product that I am not able to find a good name or definition for.
