This applet finds all abelian powers in a partial word over an alphabet of at most four letters. In the first text box, use 'a,b,c,d' to denote letters and use '^' to denote a hole. In the second textbox, enter an integer. This applet will then only consider abelian powers of this order or greater. In the third textbox, enter an integer to be the abelian power that will be checked. Check the 'Print Abelian Powers' box if you would like this applet to print all abelian powers it found.

To run this program, all you will need is the latest java plug-in.

Keywords: Combinatorics on Words; Partial Words; Abelian Powers.
