using a
method of
construction devised by Cantor, a
bijection will be
constructed between T and R. Therefore, T and R have the same...

- In
graph theory, an
isomorphism of
graphs G and H is a
bijection between the
vertex sets of G and H f : V ( G ) → V ( H ) {\displaystyle f\colon V(G)\to...

bijection can
exist between {1, 2, ..., n} and {1, 2, ..., m}
unless n = m; this fact (together with the fact that two

According to the
second meaning, a
permutation of a set S is
defined as a
bijection from S to itself. That is, it is a
function from S to S for
