Just as I was drifting off to sleep last night, I remembered that Don
had proposed allowing to null change to enable 240s of Doubles with each
row at hand and back.
This is unnecessary. Some years ago, I produced 240s with this property,
but using conventional bobs and 123-singles. This was to enable certain
asymmetric doubles methods to be rung and named. (Not all - some yield
Group A (Plain)/B(RC) produced these (amongst others):
PBPBPSPBPSPS x 2
The groups with plain-hunt as the lead end were even more efficient:
PPBBPPBBPPBP x 2
This is, of course, the standard extent with an omit at the end.
