First of all, thank you Don for the automatic method classifier.
34.45,4
Lead-end 3124685079
6 leads, 24 change round block
>From a construction point of view:
Front 3 bells plain hunt
4 is fixed
Back 6 treble bob
The hunt bell is 4.
differential hunter
4 has a well formed path
Not a plain hunt method as 4 blows in each position in the lead
so Treble Place as same number of blows in each position of its path > 2
bell 4 doesn't cover all the positions => Little
Differential Little Treble Place Royal
but consider other lead lengths for the same plain course:
34.45.34.4.34.45,4
so bells 1,2,3 and 4 are hunt bells
4 stays in 4ths
1,2,3 plain hunt, however they make more than 2 places, so it is still
Treble Place.
If you consider the whole course as a lead
34.45.34.4.34.45.34.4.34.45.34.4,4
then it isn't officially a method, but relaxing that then every bell is a
hunt bell, and the treble dodging test C.1.(b) gets satisfied first, then
it becomes surprise because of the 'internal place' at the cross-section
(by bell 4, also 5ths is made). That seems a bit odd as the place is
outside the range of the hunt bell and it still looks more like treble
bob.
Another interesting case might be
x6,67
Plain hunt on the front six, treble bob on the back four
x6x67
Differential Royal
x6x67x6x67
Differential Royal
x6x67x6x67x6x67
Little Bob Royal - as the front six have returned home
x6x67x6x67x6x67x6x67
Differential Little Surprise Royal - as the back four have returned home
x6x67x6x67x6x67x6x67x6x67x6x67
Differential Little Treble Place Royal - the front bells have returned
home, but made more than 2 places
x6x67x6x67x6x67x6x67x6x67x6x67x6x67x6x67x6x67x6x67x6x67x6x67
Differential Little Treble Place Royal - if this were to be treated as a
method then all the bells return home, but the plain hunt test fails for
the front 6 as there are more than 2 blows in each position, and the
treble bob test fails as there more than 2 places (two whole treble bob
cycles). I think that all the hunt bells are treble place hunts.
The Little Surprise versus Little Treble Bob question still puzzles me a
bit. If you have multiple little treble bob hunt bells then the extreme
place of one the hunt bells counts as an internal place for the others and
can convert the type to surprise or delight.
Consider a variation of the above, with the plain hunt out of phase so it
doesn't have a place at the treble bob cross section.
6x6.7
so
6x6.7.6x6.7.6x6.7.6x6.7
is Differential Little Surprise Royal as the 7ths when one of the hunt
bells turns around counts as an internal place for the others. Trying to
adjust the rules to make this Differential Little Treble Bob Royal might
be tricky though, and adding complexity won't be popular.
The lead versus plain course question for defining methods is intriguing.
Is my example x6,67 etc. one method or several?
In terms of Don's contractions/extensions
34.45,4 Major is a false method
34.45,4 Minor is a false method
See http://www.methods.org.uk/ccdecs.htm#decGD
D. Extension of Little methods, principles and differentials by an even
number of stages
so is it a mode-5 extension from the minor,major?
