Interestingly the operations of "moving by an interval from one note to another" as is being discussed at length under "query about compound intervals..." form a group. But only if you consider "directed intervals" (otherwise there is no inverse). I think this one of the things which underlies my eschewing the consideration of positive intervals only.
