This can be done by typing only 'i' or maybe Control-'i' without complicated math. The advantage is that our lookup table has only 33 letters or so instead of more than 300. This saves memory and searching time. The WP macro language had limited logic capabilities and so Fidel had to be ordered logically. An obvious flaw in the above ordering is that it makes for an unnatural sorting order.
Sorters usually rely on character addresses.
The modulo ordering is then NOT recommended as an address encoding system for Fidel. The merits of the ordering is purely its algorthmic fascilitations and as such should be used only for internal modeling of Fidel by applications.
