An example of a bijection is the identity function 1X:X->X that maps each x in X to itself.
An older, more human-readable name for a bijection is "one-to-one correspondence". However, as this is easily confused with "one-to-one function", the older name for an injection, mathematicians use the newer, more precise (but less friendly) terms.
