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.
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.
