Feb 20, 2016 at 1:21 comment added Omar Antolín-Camarena Are you sure the category described in the nLab is a groupoid? It doesn't sound like it to me (the vertical maps are in $w$, not isomorphisms).
Feb 19, 2016 at 21:13 comment added Zhen Lin It is definitely not the nerve of a groupoid. If it were then $(\infty, 1)$-categories would be the same as $(2, 1)$-categories.
