OrdinalNumber

   

An ordinal (or ordinal number) may be defined in terms of surreal numbers as a (surreal) number of the form ``{L|}`` (ONAG (2001) p.79). The first infinite ordinal is ``omega = {0,1,2,3,cdots|}`` — and there are many, many more after that!

Ordinal numbers in general appear not to be of much importance in CGT as applied to go, so we need say little more here and now.
