We consider the following Problem:

  Strict Trs:
    {  i(x) -> x
     , op(i(x), op(y, op(z, w))) -> op(x, op(z, op(y, w)))
     , op(i(x), op(y, z)) -> op(x, op(i(i(y)), z))}
  StartTerms: all
  Strategy: none

Certificate: MAYBE

Proof:
  None of the processors succeeded.

  Details of failed attempt(s):
  -----------------------------
    1) 'matrix-interpretation of dimension 4' failed due to the following reason:
         The input cannot be shown compatible

    2) 'matrix-interpretation of dimension 3' failed due to the following reason:
         The input cannot be shown compatible

    3) 'matrix-interpretation of dimension 2' failed due to the following reason:
         The input cannot be shown compatible

    4) 'matrix-interpretation of dimension 1' failed due to the following reason:
         The input cannot be shown compatible
