& just to try for completeness
it looks like there may be yet another border arc
on neng not far from bjneng
with a radius of 100 miles
so probably the largest such on earth
but of unknown curvature length
http://www.law.fsu.edu/library/collection/LimitsinSeas/IBS093.pdf
supposedly it is centered on sokoto
but is still not obvious at this scale
http://www.lib.utexas.edu/maps/africa/niger_2000_pol.jpg
in fact i am in process of reviewing all the old borders between
british & french spheres of influence of the same approximate
period
where still other arcs might almost be expected to be lurking
on stylistic grounds alone
but even so
& even counting itva as 5 distinct curves
as i believe is technically correct
rather than only 1 or 3
i believe i may still hope to count all the border arcs in the world
on my fingers & toes alone
