Problem:
 f(h(x),y) -> h(f(y,f(x,h(a()))))

Proof:
 Unfolding Processor:
  loop length: 6
  terms:
   f(h(h(x758)),h(h(x986)))
   h(f(h(h(x986)),f(h(x758),h(a()))))
   h(h(f(f(h(x758),h(a())),f(h(x986),h(a())))))
   h(h(f(h(f(h(a()),f(x758,h(a())))),f(h(x986),h(a())))))
   h(h(f(h(h(f(f(x758,h(a())),f(a(),h(a()))))),f(h(x986),h(a())))))
   h(h(f(h(h(f(f(x758,h(a())),f(a(),h(a()))))),h(f(h(a()),f(x986,h(a())))))))
  context: h(h([]))
  substitution:
   x758 -> f(f(x758,h(a())),f(a(),h(a())))
