        We apply a matrix interpretation of kind constructor based matrix interpretation:
        The following argument positions are considered usable:
          uargs(c_7) = {1}
        
        Following symbols are considered usable:
          {a__c#,a__f#,mark#}
        TcT has computed the following interpretation:
           p(a__c) = [0]         
           p(a__f) = [1] x1 + [1]
              p(b) = [2]         
              p(c) = [0]         
              p(f) = [1] x2 + [8]
           p(mark) = [0]         
          p(a__c#) = [0]         
          p(a__f#) = [8] x1 + [1]
          p(mark#) = [2] x1 + [6]
            p(c_1) = [1]         
            p(c_2) = [1]         
            p(c_3) = [1]         
            p(c_4) = [2] x2 + [0]
            p(c_5) = [4]         
            p(c_6) = [1]         
            p(c_7) = [1] x1 + [8]
        
        Following rules are strictly oriented:
        mark#(f(X1,X2,X3)) = [2] X2 + [22] 
                           > [2] X2 + [14] 
                           = c_7(mark#(X2))
        
        
        Following rules are (at-least) weakly oriented:
