Sets of offices (8)
I believe the answer is:
stations
I believe this is a double definition.
'sets' is the first definition.
(both can mean assign to particular place)
'offices' is the second definition.
(both can mean buildings where something happens)
'of' acts as a link.
(Other definitions for stations that I've seen before include "Bases, posts" , "Roman Catholic devotions of the Cross" , "Stopping places as for railway trains" , "Railway halting places" , "RC devotions of the Cross" .)
