Alan Burbidge's new peal 
is a attractive addition.

It is based on group 5.03 of order 20, generated by 1245673, 1235746.
This is the same group as Thurstans', but with 12 fixed.

Here are the blocks, as generated by my search program
QS means a quick six, SQ means a slow six, the choice of starts is
just how the program happens to work.
These have 4*20 singles, 7*20 bobs, 31*20 plains in 10 round blocks.
With luck these can be linked with 9 pairs of singles replacing plains.
(Replacing a pair of singles with plains might not work because 
replacing them everywhere would probably have lead to sets of blocks
with fewer calls which would have been discovered at an earlier stage).

The second type of block can be linked to the first with a pair of
singles to form 2 round blocks based on group 5.05 of order 10.


If the singled-in section is omitted in part 6, and added back as an
extra 2 courses to the 2 courses of the singled-in section in part 1,
the peal results.

Singled-in section 
is actually two parts
and for part 1 is

You can see the 20-part structure as the 5th course-end as published
is 2613574, giving a part-end 1263574.
