Properties of a ternary infinite word

Abstract

We study the properties of the ternary infinite word p = 012102101021012101021012 that is, the fixed point of the map h : 0 ->01, 1 ->21, 2 ->0. We determine its factor complexity, critical exponent, and prove that it is 2-balanced. We compute its abelian complexity and determine the lengths of its bispecial factors. Finally, we give a characterization of p in terms of avoided factors.
