I define a method as a specification of a sequence of changes. That can include:-

Methods made up of an  unvarying sequence of changes i.e. statically defined by a sequence of place notation.

and...

Methods where the changes are determined by rules based upon the position of bells in the previous row(s) i.e. dynamically defined or Dixonoids.
