I have created tag-wiki and tag-excerpt simply containing the first sentence of the Wikipedia article. (So that the tag-wiki is at least non-empty.)
You know about the topic more than I do, feel free to expand the tag-wiki. But at least I suppose we can agree on the fact that tag was intended about the questions from group theory, not for some other types of growth.
Feel free to ping me if you add something to the tag-info or if you have something more to add to the discussion of this tag @kneidell
If you can find some other question(s) where this tag is appropriate, maybe you could add it to such question. (At the moment there is only one questions with this tag. As mentioned before, tags with only one questions are removed during tag clean-up, which is done by the system regularly.)
(On the other hand, if someone thinks the tag is worth preserving, it would be good to add at least one other question. I do not know anything about this topic, so I do not feel confident enough to add the tag to some questions. Maybe some questions shown when searching for subgroup growth among questions tagged group-theory could be suitable candidates.)
