Since the set/sequence doesn't have a largest/last element, it is rather
hypothetical, yes. :-)

What is meant by the expression: 1/infinity ?
I assume I know what you mean by '1', but I don't know what you mean by
'/infinity'.

If I search for: ordinal arithmetic division
I find: http://www.infidels.org/library/modern/graham_oppy/t_finite.html
Which sort of explains why our teacher only taught us + and * on transfinite
ordinals, never - and /...
