That is, from the Thue–Morse sequence one forms a new sequence in which each term is the difference of two consecutive terms of the Thue–Morse sequence. The resulting square-free word is Another example found by John Leech is defined recursively over the alphabet {"a, b, c"}. Let formula_1 be any word starting with the letter "a". Define the words formula_2 recursively as follows: the word formula_3 is obtained from formula_4 by replacing each "a" in formula_4 with , each "b" with , and each "c" with . It is possible to check that the
