Someone just created this tag today, and added it to three questions. As written, the description is... the most generic thing ever, basically "anything associated with permutation groups and permutation cycles". Given that there is already a (permutations) tag, what purpose does the (permutation-cycles) tag add?
Also why is the (permutations-group) tag a synonym for (permutations)? There are lots of cases where people are dealing with problems involving permutations, but not working with a group.
