New category, groups of three.

For example. Weber’s three basic legitimation’s of domination:

1. The authority of the ‘eternal yesterday’.
2. The authority of the extraordinary and personal gift of grace, aka charisma.
3. The domination by virtue of ‘legality,’ e.g. rule based and professionalism.

I should have started this category years ago, say when I wrote about my affection for having three models.
