[r-t] Method symmetry

[Alexander Holroyd]

This prompts the following question, reminiscent of the "unprinciples" 
discussed a few moths ago:

Is there an asymmetric method in which the work of every bell is 
symmetric?

Actually, the answer is yes.  E.g., ring plain bob minimus on the front 
and back 4s of 8, out of phase by an amount that is neither 0 nor 4 rows. 
E.g.

http://www.boojum.org.uk/cgi-bin/line.pl?bells=8&pn=-1458-1458-1456-1258&qs=Grid&action.x=1

But are there some more interesting examples?
