Concept
How can we make a mapping bijective?
Stephen Davies, Ph.D. Version 2.2.2 Through Discrete Mathematics A Cool Brisk Walk / Chapter 1
"that it’s bijective? One way is to add a third sport — say, kickboxing — and move either Julie or Chuck over to kickboxing. If we have Julie map to kickboxing, Sam map to volleyball, and Chuck map to basketball, we have a bijec- tion."
