Paul,
I looked at the article and I understand that for that particular case.
However that case fell back in the definition on an already existing
infinite domain of the same order namely Z. There is also a similar
definition in the Book for Odd numbers.
In my case I cannot fall back on an existing finite domain, or I do not
know how to explore/exploite it with Boolean.
I am thinking of a domain named Irany having elements
{North,East,South,West}. How can I do that without a reference to a
more basic domain as foundation and expect that
Element[NorthWest,Irany] will give me False?
Thanks ahead,
János
