What does bijection mean?
noun
A bijective function or relation is a mathematical function or relation between the elements of two sets, where every element of one set is paired with exactly one element of the other set, and every element of the other set is paired with exactly one element of the first set.
Example
"The bijection between the set of integers and the set of rational numbers is not a surjection, because not every rational number has an integer as a preimage."
