MAYBE
We consider the system theBenchmark.

We are asked to determine termination of the following first-order TRS.

  a!6220!6220and : [o * o] --> o 
  a!6220!6220length : [o] --> o

  cons : [o * o] --> o 
  length : [o] --> o 
  mark : [o] --> o 
  nil : [] --> o 
  s : [o] --> o 
  take : [o * o] --> o 
  tt : [] --> o 
  zeros : [] --> o
