Date: Mar 2, 2012 10:11 AM Author: Mahesh Subject: Cross product I came across following while reading about associativity of cross product of two sets:

For three sets A,B,C

(A X B) X C is generally same as A X (B X C) but there may be exceptions where associativity dos not hold.

Can anyone give any example when cross product does not hold the associative property?
