  Strict Trs:
    {  a(b(b(b(a(x1))))) -> b(b(b(b(a(b(b(b(b(x1)))))))))
     , a(b(b(a(a(x1))))) -> b(b(a(b(a(b(b(b(a(x1)))))))))
     , a(b(a(b(a(x1))))) -> b(a(b(b(a(b(b(a(b(x1)))))))))
     , a(b(a(a(a(x1))))) -> b(a(a(b(a(b(b(a(a(x1)))))))))
     , a(a(b(b(a(x1))))) -> a(b(b(b(a(b(a(b(b(x1)))))))))
     , a(a(b(a(a(x1))))) -> a(b(a(b(a(b(a(b(a(x1)))))))))
     , a(a(a(b(a(x1))))) -> a(a(b(b(a(b(a(a(b(x1)))))))))
     , a(a(a(a(a(x1))))) -> a(a(a(b(a(b(a(a(a(x1)))))))))
     , a(b(b(a(x1)))) -> b(b(b(a(b(b(b(x1)))))))
