- - - - some elements of S may not be related to T
  - - - All elements of S are related to an element in T
  - - - some elements of T may not be related to an element in S
  - - - Set containing all Injective functions which are also a total function S to T
  - - - Every element of T are related to some element in S
  - - - Set containing all Surjective functions which are also a total function S to T
  - - - Total, Injective and Surjective
  - - - Returns the size of a given sequence
    - - Receives 2 sequencies and returns one sequence from putting together the input
    - - Returns the reverse of a given sequence s
    - - Prefixing an element e in s returns a sequence whose first element is e and the rest is the sequence s
    - - Returns the first of a non-empty sequence s
    - - Returns the first of a non-empty sequence s
    - - Retrurn all elements but the last
    - - Retruns the first n elements of s
    - - Removes the first n elements of s
    - - non-empty sequences containing elements of s
    - - Total functions of S
    - - Injective sequences containing
        elements of S (no repetition)
    - - All permutations of S
