    Input format:

    

        

            For quiver:
            
 Quiver( [..
                list of vertices ..], [..[src,tar,arr_name]..] ) 

            "Quiver()" can be omitted.
        

        

            For relations:
            
 [ ... list
                of relations ... ] 

        

    

    

        Usage:

        (1) Input data and click "Translate to QPA" button 

            [Optional] Modify result in the ouput box
            [Optional] Click "Save to .sba file" to save the
        output to a file named
        ".sba", if wanted

        (2) Click "Transfer to String Applet"
        (I thank Jan Geuenich for extending this
            functionality!)

        

    

    

        Known Limitation:

        - Only less than 25 vertices allowed.

        - Display of quiver in the String Applet can be ugly; one needs to manually move the vertices around to get
        better view.
        

        - Can only detect finite field of characteristic at most 61
