   I fixed a typo in the big diagram, but I don’t know how to fix this typo:

   skeletal groupoids $C_k$ of $C_0$ for $k \geq 0$ indexed by $C_0$,

   I fixed a typo in the big diagram,

   Thanks. I fixed a bunch more typos and further expanded the entry by more definitions, more propositions and more examples.

   That “of” doesn’t sound right to me!
