Here are four possibilities for Lundy Differential Surprise (or Sgurr
Differential Surprise):

<http://ringing.org/main/pages/dfm/royal/single-surprise/l#11758>
<http://ringing.org/main/pages/dfm/royal/single-surprise/l#11759>
<http://ringing.org/main/pages/dfm/royal/single-surprise/l#11760>
<http://ringing.org/main/pages/dfm/royal/single-surprise/l#11761>

The last two highlight an amusing asymmetry in the CCCBR's Decisions.
They allow either of these callings to be described as a single method
composition of Lundy Differential, but prohibit their description as a
single method compositions of Ingoldsby.
