Tetration is the hyperoperation which comes after exponentiation.[1] means y exponentiated by itself, (x-1) times.[2][3] List of first 4 natural number hyperoperations:

  1. Addition
    a succeeded n times.
  2. Multiplication
    a added to itself, n times.
  3. Exponentiation
    a multiplied by itself, n times.
  4. Tetration
    Note (operator associativity):
    a exponentiated by itself, n-1 times.

The above example is read as "the nth tetration of a".
