A quick Google gives the following links for some inspiration:

http://mathworld.wolfram.com/CrossProduct.html

http://steve.hollasch.net/thesis/chapter2.html

http://www.mathpages.com/home/kmath069.htm (see "Generalizations to 
Higher Dimensions").

Mathematics isn't my area of competence (a hopeful phrase implying that 
I may actually have one), so I'll leave it to minds more familiar with 
such things to determine what should be implemented.

Richard
