Thank you all for your comments. I found Richard Smith's article very 
interesting, it really goes to show how many different ways truth can be 
defined in different contexts.

Has an "extent" of 20,160 Little Bob Major ever been rung? It seems like 
something that should be done at least once before the human race 
becomes extinct.

It also brings me back to a question I asked after a peal a year or two 
back: Is it possible to ring a 2,880 of Surprise Minor where each change 
appears once each at each position of the treble? That is to say that, 
for example, 135246 appears once at the treble's backstroke snap, once 
at the handstroke snap and at each of the lead end positions. Further 
than this, is it possible in general for any treble bob method 
(symmetric or asymmetric). If not, what are the conditions for being 
able to do it? It may be very trivial, but I haven't managed to come up 
with an answer myself.

Thanks,
Joe.
