[r-t] Unprinciple extent!

[Mark Davies]

I have to say I agree with Graham. The way Ander has written out the 
place notation for his method makes it pretty clear. It would be a lot 
simpler to think of it as the following much shorter and far less samey 
twin-hunt method:

	&-4-1.4.3.4-4-, 23

With a 234 bob the 720 becomes simply 4x(pp-p).

So this example is, again, in some sense reducible to a smaller 
non-unprincipled method.
