  bijection
  
     <mathematics> A {function} is bijective or a bijection or a
     one-to-one correspondence if it is both {injective} (no two
     values map to the same value) and {surjective} (for every
     element of the {codomain} there is some element of the
     {domain} which maps to it).  I.e. there is exactly one element
     of the domain which maps to each element of the codomain.
  
     For a general bijection f from the set A to the set B:
  
     f'(f(a)) = a where a is in A and f(f'(b)) = b where b is in B.
  
     A and B could be disjoint sets.
  
     See also {injection}, {surjection}, {isomorphism},
     {permutation}.
