This is getting deep. It is an embarrassing metamathematical fact that numbers cannot be defined. At least, mathematicians gave up trying a century ago. In mathematics, the essence of counting a set and finding a result n, is that it establishes a one to one correspondence (or bijection) of the set with the set of numbers {1, 2, ..., n}. <URL: https://en.wikipedia.org/wiki/Counting#Counting_in_mathematics> Our ancestors defined the fingers (or digits) as "the set of numbers." Modern mathematicians have managed to enhance the definition quantitatively but not qualitatively. Marko -- https://mail.python.org/mailman/listinfo/python-list
