Thanks
for clarifying this. My language (spiro...) comes from chemistry, the subject I
graduated in. A spiro binding occurs in organic molecules where a ring is
bound to another ring just with one carbon atom that belongs to either ring.
This is the situation on Sorgschrofen, and you are right: at the Visweg in
Baarle as well. Bengal I am unable to confirm.

if i
understand you correctly
it is rare but not really unique
another
one occurs in baarle & a third in bengal
we have been calling these
border crosses
there are many on lower than international levels
too
the bwnazmzw quadripoint probability you mention is indeed
different
& only exists sometimes
maybe
as it involves moving
thalwegs etc
