BTW all tags used in the above question have only this once occurrence and the list of new tags says that they were created created Jul 11 at 17:32.
So this question created 3 new tags and used none of existing tags.
As a side note (not directly related to mathematical side of the question) I see that you created 3 new tags in this question. Perhaps some of already existing tags might be suitable here, for example, (combinatorial-identities) or (binomial-coefficients). (Maybe somebody will suggest other suitable tags.) If some further discussion of tags is needed, feel free to drop a line in this chat room. — Martin Sleziak36 secs ago
However, the main point I am trying to make that it is probably better to be a bit careful about creating new tags. And using some of the established tags might improve the chance that the question gets noticed, especially if some of the tags with many followers is a good fit for the question.
