In this paper, we investigate the number of letters needed to construct partial words with infinitely many holes that avoid abelian 3rd, 4th, or 5th powers. Recent work showed that this number is five for 2nd abelian powers, while it is two for 6th or greater powers.
Keywords: Combinatorics on Words; Partial Words; Abelian Powers.
