Iterated Map
An iterated map is a map that is applied repeatedly to an object. The Wolfram Language function
NestList[f,
expr, n] gives a list of the results of iterating the function 
times on the initial expression expr.
Similarly, Nest[f,
expr, n] gives the last element of this list, i.e., the result after
iterations.
