Consequently, they are able to capture highly mobile, sensitive prey. We used digital p...

This article is about the mathematics of ringing the changes. We describe the mathematics which arises from a real-world activity, that of ringing the changes on bells. We present Rankin’s solution of one of the famous old problems in the subject.
