Let A={1,2,3,4,5,6} and consider the following 3 subsets of A. A, = {1,3,5}; Az : %3D %3D %3D {2,4, 6}; A3 = {3, 6}. Define the relation R on set A as follows: x R y if and only if {x,y}C A, or {x,y}C A, or {x,y}C A,. That is, x R y if and only if x and y are both in A1 or x and y are both in A2 or x and y are both in A3.
