Problem:
 a(b(x1)) -> x1
 a(c(x1)) -> b(b(x1))
 c(b(x1)) -> a(a(c(c(x1))))

Proof:
 RT Transformation Processor:

  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [c](x0) = x0 + 7,
    
    [a](x0) = x0 + 5,
    
    [b](x0) = x0 + 24
   orientation:

    a(c(x1)) = x1 + 12 >= x1 + 48 = b(b(x1))
    
    c(b(x1)) = x1 + 31 >= x1 + 24 = a(a(c(c(x1))))
