There are probably as many Frieze Group ( and Wallpaper Group ) 'guesser programs' as there are programming languages. I chose a Frieze Group guesser that has been written in Mathematica.
If you don't have Mathematica, there is a free Mathematica Player. There are also Student and Home Editions ( with all functionality ) at a much reduced price.
