Techopedia Explains Kleene Star

The Kleene star, which is useful in the building of “automata” or automated systems, is described mathematically as a “unary” operation or a “free monoid” construction. It is described as a possible set of strings that can be created by concatenating elements of a base string. In other words, each individual element of the input string must be present, but additional elements can be repeated to any extent.
