```Have managed to produce a 5040 for challenge 1...whether it meets challenge
2, who knows!

I had a very similar idea to Robert, which was to come up with a Plain
method that could carry out the task: 5.147.5.3.147.3,147  1342756.

'Bobs' are substituted 5s or 3s that don't affect the treble. To overcome
the parity barrier, the treble gets affected by occasional 'calls,' thereby
producing long and short leads in those instances. This automatically
created a building block for a very nice 18-part structure.

The peal uses group 6.12 from Price's paper, which is generally not
possible for extents in almost any method you can think of on 6 or 8 bells
(though it has been used before for at least one Triples extent.)

I guess it is also quite rare for a peal to have calls everywhere except at
