On ternary Dejean words avoiding 010
Thue has shown the existence of three types of infinite square-free words over {0,1,2} avoiding the factor 010. They respectively avoid {010,212}, {010,101}, and {010},{020}. Also Dejean constructed an infinite (7/4⁺)-free ternary word. A word is d-directed if it does not contain both a factor of le...
