Try to guess 20 (actually, 21 due to tie-in) first level administrative subdivision capitals (both in Austriaa and other countries) closest to Innsbruck.
For practical reasons, I'll make some exceptions:
For Slovenia and Northern Macedonia, only largest city in every statistical region is included.
For Luxembourg, Liechtenstein, San Marino and Andorra, only country capital and largest municipality seat are included.
If some subdivision capitals are omitted but should be included, please let me know.
If speakers of languages that don't use latin script consider I should include different transliteration of city names, please let me know.
