Taking an example from category theory, given a category "C", the opposite category is usually denoted "C^op". Where "op" is an abbreviation for opposite. Now there are three ways to put this in latex:
- As
C^{op}
- As
C^\operatorname{op}
- As
C^\text{op}
While I wouldn't use the first one, thw second and third both make sense to me in some way. So is their a convention which one should use, and if so, what's the reasoning behind it
