[r-t] 147 TD Minor all the work

I have managed to get the standard 147 treble-dodging minor into an all-the-work composition of 18720 (26 extents).  This is one extent more than the obvious lower bound of 18000 (25 extents), which applies because 5 leads of each method makes 24.5 extents.  I would not be surprised if an 18000 exists, but I have not found one.


I think the previous record was 20160 (28 extents), first achieved by Richard Smith, beating an earlier record of 21600 (30 extents) by John Warboys.  (Please correct me if I have any of this wrong).

In contrast with these, this one is a 5-part.  Moreover, it contains plain leads of every method.  Consequently there are very few calls (only 6 per part, in fact).  (I know some people are not so much into this style of composition - that is a matter of taste).

In fact, the leads of the composition can be separated into two 9360s, containing respectively all the Surprise and 4ths place Delight methods, and all the Treble Bob and 3rds place Delight methods.  It is very striking that the former exists: there are only 2 "leads to spare" in the part.  The latter can be arranged to have plain leads of every method.


It is not possible to get all the TB and 3D methods in the obvious lower bound of 8640 in a 5-part (always assuming my code is correct).

Finally, the last two compositions can simply be bolted together part by part to get a different 5-part 18720 (this time without the "plain leads" property).
