[r-t] Spliced TD Minor (147m)

[Philip Earis]

Hi people,

If you apply the 'standard' criteria that give the 41 surpise minor
methods (ie plain-bob leadheads, no more than two consecutive blows, no
single changes, no places made in 5ths above the treble, having the
right parity structure to generate the extent) to treble-dodging minor
methods, you get 147 methods.  

The 147 methods have only been rung together twice, both last year in
all-the work peals, composed by John Warboys and Richard Smith.  Both of
these peals were over 20k changes.

However, I'd also quite like to ring a shorter (not-atw) peal of the
147.  I think minor ringing is in a golden age at the moment, and quite
a few people would be keen to ring a peal of the 147 if it was
sufficiently short.

I therefore have two questions:

1) What is the shortest length composition that includes all 147
methods?

2) How many of the 147 can be squeezed into 7 extents?

John has a composition we've rung for 113 of the methods in 7 extents on
his website (http://website.lineone.net/~jswcomps/) - is this the
maximum?
