Then is said to be an injection (or injective map, or embedding) if, whenever , it must be the case that . Equivalently, implies . In other words, is an injection if it maps distinct objects to distinct objects. WebbTo count the number of one-to-one (injective) functions, all we need is 1 and 2 must map to distinct elements. If the function is one-to-one, then the number of choices for 1 is n. Once we know where 1 has been mapped to, the number of choices for 2, so that the function is one-to-one, is n − 1.
