If we replace a single with a plain lead we have to replace a further 
four because of the q-set involving the 'bob' part. If rounds occurs at 
a plain lead head, then so must


But we also deal with the 'single'. Either 235476 or 324567 also has to 
be a plain lh.  At first  sight either could be, but choosing 324567 
means we can't plain any of the q-set containing 235476 - this forces 
the choice for the other four singles, and we soon end up with every 
possible lh. Thus 235476 and the rest of its 'bob' q-set are plain lhs:


Thus q-sets have 10 elements.

However, each q-set we plain rules out another five.

If we plain just one q-set, we join ten blocks together, with every 6th 
lead being a plain lead of alternately Grandsire and 'New Grandsire'. It 
may be possible to get a peal length this way, but I am sure that with 
the limited room to manoeuvre one where all the plain leads of the same 
type would not be.

Look at the blue line.

A bob followed by an omit two blows later?
