This looks impressive to me:

Thoughts?

Cheers

It looks that way, but this is another example of where complib does not 
help conductors.? Conductors would need to rewrite this in a more 
intelligible form.? Well done on the compo though Thomas.

Have we discussed this? I can't remember doing so. I think it contains 
all 4-runs, including internal ones. I note no-one has rung it! Does 
anyone know Richard?

There is a Composition Request thread on complib for this
(https://complib.org/issue/420). Richard thinks he can get it down to
5000, but accepts that his composition is an exercise in proving it is
possible rather than something anyone would ever ring.

I think there are 176 places in that composition where you could omit
two changes with a half-lead 1234 single without losing any runs, but
the resulting 5008 would be even less ringable.

Surely this is a ringing and conducting challenge that someone will take 
up?!
