[OSM-dev] How to find the way with the most relation memberships

[Roland Olbricht]

Hi,

https://overpass-turbo.eu/s/BpE
shows that this has happended already 2015 and in changeset 33711981. It 
is notable that
- the user made otherwise many useful contributions
- there are two version fo that relation within the changeset, only 6 
minutes apart
This makes it most probable that the editor (an old Potlatch version) 
had a bug, and that the bug most likely had been fixed long ago.

The other affected relation 5328067 (replace twice in the query) is from 
the same changeset and has the same number of duplicate members, which 
also is well in line with an editor bug.

Best regards,

Roland
