I noticed for the first time today that there is a (block-design) tag, with no description and 12 questions. It seems that this tag is completely redundant, as there is already a (combinatorial-designs) tag (which does have a description, 154 questions, and is the exact same thing). Should this tag be removed/merged?
(This is my first post on meta so I don't know if I'm phrasing this question correctly. Any feedback is appreciated.)
