... an alphabet A is a left (right) maximal Abelian square-free string if, for every a ∈ A, ax (xa) contains Abelian squares. An Abelian square-free string is maximal if it is both left maximal and ... which is a square. Less studied is another kind of repetition that can occur as a substring of a string, called an Abelian square. An Abelian square is a string followed by a permu...
