Abstract
The exponent of a formal word is the relation between its length and its minimal period. A repetition (subrepetition) in a word is a factor of exponent not less than 2 (less than 2). A gapped repeat in a word is a pair of identical factors with a positive gap between these factors. In the paper we present a review of some new results concerning the possible number of repetitions, subrepetitions and gapped repeats in words of fixed length .
