I didn't make my objection lightly. The problem of ordering and
sequence has cropped up over and over again in the last few years.
I have seen many definitions. Most definitions seem to rely on being
able
to tell left from right. Now how are you going to mathematically
represent that? It
seems that it is merely assumed.
I assure you, there is no foolproof way of establishing order.
