Homework Statement
Let [itex]X= \{a,b,c\} [/itex] and [itex]Y= \{d,e\}[/itex]. Write down and explicit bijection [tex]N_{|X×Y|} → X×Y[/tex]
The Attempt at a Solution
Well I came up with the easiest method, just giving one value to each member of [itex]N_{|X×Y|}[/itex] so I was just wondering whether there is another way of doing it not by brute force? :)
