[r-t] MUG Minor Revisited

[Graham John]

MUG Minor is a principle that has been discussed several times on this
list. As a teenager in the 1970s, I tried and failed to find an extent with
standard 14 bobs and 1456 singles using pen and copious amounts of paper.
Brian Price nicknamed it the Cussed Principle, presumably because
intuitively it seems that an extent should be possible but he could not
find one. Ander Holroyd finally produced an extent in 2004 using half lead
calls, and this featured in the Compositions of the Decade articles by
Philip Earis written in 2009 (
http://wiki.changeringing.co.uk/Compositions_of_the_Decade_3_-_Minor).
Recently, I noted that a quarter of MUG Minor had been rung in 2002 (
https://bb.ringingworld.co.uk/view.php?id=445519) saying that the 1280 used
a composition of Brian's using 14 and 36 leadend calls. This led me to
revisit it, but this time looking for a quarter peal length. I found this
solution using standard bobs only. This rotation has the treble as
unaffected observation, avoiding internal rounds and 65s at back. All the
leadheads are distinct.
