Deletion of Math symbol e (disambiguation)

Comment: A clear case of |incomplete disambiguation. (This is a disambiguation, not a set index article, because it's centered around unrelated topics with the same name rather than topics whose name similarities are a consequence of their relatedness.) If this had any chance of being used, a redirect would be appropriate, but who's going to link to this name
Stance: delete
