Abstract

We propose a new ternary infinite (even full-infinite) square-free sequence. The sequence is defined both by an iterative method and by a direct definition. Both definitions are analogous to those of the Thue–Morse sequence. The direct definition is given by a deterministic finite automaton with output. In short, the sequence is automatic.
