The weightgap principle applies (using the following constant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(c_1) = {1}, Uargs(c_2) = {1}, Uargs(c_4) = {1},
  Uargs(c_5) = {1}, Uargs(c_7) = {1}

TcT has computed the following constructor-restricted matrix
interpretation.

        [a] = [0]           
              [0]           
                            
    [c](x1) = [0]           
              [0]           
                            
    [d](x1) = [0]           
              [0]

    [g](x1) = [1 0] x1 + [0]
              [0 1]      [1]
                            
  [f^#](x1) = [0]           
              [0]           
                            
  [c_1](x1) = [1 0] x1 + [2]
              [0 1]      [2]

              [0]

The order satisfies the following ordering constraints:

  [f^#(c(b()))] =  [0]               
                   [0]

                =  [c_6()]           
                                     
    [e^#(g(X))] =  [1 1] X + [1]     
                   [0 0]     [0]     
                >  [1 1] X + [0]     
                   [0 0]     [0]     
                =  [c_7(e^#(X))]     
                                     

Further, it can be verified that all rules not oriented are covered by the weightgap condition.
