Adjacent NUTS3-regions

Dear all,
I am trying to find out which NUTS3-regions are directly adjacent to each other. Is there by chance already a script or a list with that information? Or a list that inlcudes the NUTS3 codes and center geo-coordinates?
Best regards,
Sebastian

Wikidata contains this type of contextual info, for example for the Ile-de-France région : NUTS code with shares border with. You could query Wikidata to get a nice table with the same data for all EU regions.

Great thanks! I am trying to figure out the queries, but it seems to get me exactly what I need!

You can download the polygons from the GISCO repository. Then finding the adjacencies is a typical GIS problem: here is a way to do it using QGIS, here in Python using GeoPandas.
