Here is a little background on this Major series of puzzle caches. In tower bell ringing there are many possible ways to ring the bells so that they change in the order in which they are rung, and do not repeat a particular order of the bells during the piece of ringing. This is the theme that underlies the idea of change ringing rather than tune ringing. One particular family of methods to enable this to happen in a piece of ringing that could be rung on 8 bells is called surprise major.
Surprise Major Methods might be named after major cities like Bristol or London, specific places such as Woolwich Ferry or Stonehenge or maybe particular villages such as Knutsford, Flixton or Grayshott that might have had particular significance to those that rang the method first in a peal and so had to name the method to define what they rang.
Since there are several thousand possible surprise major methods that have been devised several other naming schemes have also been used. There are elements such as Chromium or Darmstadtium that were often rung for the first time on the bells at Barrow Gurney. Methods have also been named for specific occasions such as the Centenary of Scouting or Elizabeth II Jubilee. There are also those that are pure whimsy like Fantastic, Jellied Eel or even E=mc2.
